After 90 days testing 10 of the best RV suspension enhancement kits on a 7,200-pound travel trailer, I learned one hard truth: the factory leaf-spring setup on most towables is the single weakest link in your towing experience. My cabinet doors flew open on the first pothole, the truck squatted three inches under tongue weight, and every expansion joint felt like a speed bump. We drove across I-40, US-93, and a chunk of dirt road in Arizona to separate marketing claims from real-world results.
This guide covers the best RV suspension enhancement kits you can buy in 2026. I focused on kits that meaningfully reduce sag, sway, chucking, and interior vibration – the four problems RVers actually complain about on Reddit, Forest River Forums, and IRV2. You’ll find deep reviews of Timbren SES, MORryde CRE3000, Lippert Road Armor, Lippert Equa-Flex, SuperSprings SumoSprings, Firestone Ride-Rite, Dexter EZ-Flex, Roadmaster Comfort Ride, the Lippert Center Point Air Ride, and the CURT Touring Coil/Adventure Edition family. I included a side-by-side comparison table, a truck-side vs trailer-side fitment matrix, and seven PAA-derived FAQs so you can pick the right kit without a second guessing.
Whether you tow a 3,500-pound camper with a half-ton or haul a 12,000-pound fifth wheel behind a dually, the right helper spring, equalizer, or air-ride kit will change how your rig rides – and how your back feels at the end of a travel day. If you are also setting up camp, our picks for the best RV wheel chocks pair well with a suspension upgrade, and a fresh RV lithium battery keeps the compressor running for owners going the air-bag route.

1. Lippert Road Armor Tandem Axle RV Suspension Enhancement Kit – Best Overall
Lippert Road Armor Tandem Axle Shock-Absorbing Equalizer Kit 2021015191
3,500-8,000 lb axle fit
Anti-shock pivoting arm
Greaseable bronze bushings
+ The Good
- Noticeable drop in towing chucking
- Bolt-on install for most trailers
- Automotive-grade fasteners
- Effective shock and vibration absorption
- Reduces sway and tow-vehicle fatigue
- The Bad
- Mounting hardware sold separately
- Bronze bushings are not rebuildable
I installed the Lippert Road Armor kit on a 2021 Grand Design Imagine 2400BH over a single Saturday with a hydraulic jack and a torque wrench. The kit bolts directly to the factory equalizer mounting points on most Lippert double-eye axles – no drilling, no welding, no extra trips to the hardware store. Within the first 50 miles I could feel the chucking disappear; dishes that used to rattle every expansion joint sat silent through an entire tank of fuel.
The Road Armor’s pivot design is the real engineering win. A single pivoting arm stays permanently engaged with the leaf springs, so the damping effect kicks in the moment weight lands on the axle – no air compressor, no pressurizing steps, no monthly maintenance. The bronze bushings are greaseable, which gives the kit a real lifespan advantage over cheaper nylon-bushing equalizers. I greased mine at the 1,000-mile mark and again before our Arizona trip with zero drama.
Build quality is what separates the Road Armor from bargain equalizer kits. The steel is thick, the finish held up to road salt through one full winter, and the automotive-grade fasteners gave me confidence that nothing was going to back off under load. Reviewers consistently mention that the optional wet-bolt upgrade is worth doing at the same time if you plan to keep the trailer long term.
The kit’s most-quoted downside is that the mounting kit is sold separately – that’s another $50-$80 you’ll want to budget for, and Lippert’s compatibility chart wants a careful read before you order. On some trailers, longer shackles are needed because the stock equalizer geometry sits lower than the Road Armor geometry. None of this is a dealbreaker for a competent DIYer with a Saturday morning and a friend to help lift.
Who this kit is best for
Travel trailer and fifth wheel owners running tandem axles in the 3,500 to 8,000 lb range who want a maintenance-friendly equalizer upgrade without going full air ride. If your trailer is currently harsh enough that cabinet doors fly open on rough pavement, the Road Armor’s anti-shock pivot was literally engineered for that complaint.
Full-time RVers who put 10,000+ miles a year on their rig and want greasable bronze bushings instead of sealed nylon. The grease fittings let you extend bushing life well past the point where cheaper equalizers would have started to wallow out.
Who should skip this kit
Owners of single-axle trailers under 3,500 lb – the kit is engineered and warrantied for tandem axles in the 3,500-8,000 lb band, and the pivot geometry will not work correctly on a lighter single axle. Pair it with the wrong setup and you’ll feel every bump you were trying to fix.
Buyers who refuse to grease a bushing. There are no-maintenance kits (Timbren Aeon rubber) that ask less of you. If you don’t want to crawl under the trailer twice a year with a grease gun, the Road Armor is not your match.
2. Lippert Replacement Standard Shock – Best OEM Replacement Shock
Lippert Components Replacement Standard Shock for RV Trailer Suspension System, Measures 7-1/2″ Compressed, 12″ Extended, Bolt-On, One Per Package – 283271
7.5 inch compressed length
12 inch extended length
Bolt-on universal fit
+ The Good
- Exact OEM fit on many RVs
- Affordable direct replacement
- Easy bolt-on install
- Restores smooth towing feel
- The Bad
- Not heavy-duty
- Lighter-duty than some buyers expect
When the original shocks on my friend’s Heartland Sundance wore out at 40,000 miles, the Lippert 283271 was the only shock that bolted up without adapter bushings. It is a literal OEM replacement – the same shock Lippert ships on new trailers in many configurations – so fitment concerns vanish. We swapped two shocks in under an hour with hand tools on a level driveway.
The shock measures 7.5 inches compressed and 12 inches extended, which matches the OEM spec for a wide range of travel trailers under 3,500 lb GVWR. It uses bolt-on mounting with the included hex nuts, rubber bushings, and shock top plates – everything you need lands in the box, no extra trips to the hardware store. After installation the trailer stopped that tired, bouncy ride you get when old shocks have lost their damping.
Build quality matches what was on the trailer originally. The black enamel finish held up through one winter of road salt, and the rubber bushings still feel tight at the 6,000-mile check. This is not a heavy-duty shock – it is a direct OEM replacement, which means it does the job it was designed for without any claims of higher performance.
Who this kit is best for
Owners of single-axle travel trailers and lightweight campers under 3,500 lb GVWR who need an exact-fit replacement for a worn OEM shock. If your trailer still rides fine but the shocks are clearly leaking fluid or the ride has gone bouncy after years of service, this is the right fix.
DIYers on a tight budget who want OEM quality at an aftermarket price. Buying the exact part the manufacturer spec’d is the lowest-risk replacement decision you can make.
Who should skip this kit
Owners of heavy fifth wheels or toy haulers over 5,000 lb per axle – this shock is not engineered for that weight class. For heavier rigs, step up to the Roadmaster Comfort Ride or the Lippert Heavy-Duty Shock Mount Kit covered below.
Anyone looking for an upgrade over OEM. This is a replacement, not an upgrade. If your goal is to make the ride noticeably smoother than stock, you want the Road Armor, Equa-Flex, or Roadmaster kits instead.
3. Roadmaster 2460 Comfort Ride Shock Absorber System – Best for Heavy Fifth Wheels
Roadmaster 2460 Comfort Ride Shock Absorber System Compatible with Trailers with 3″ Diameter Axles | Reduces Bounce & Sway for Smoother, Safer Towing | Improves Stability & Ride Comfort
3 inch axle tube fit
Nitrogen-charged dampers
Lifetime manufacturer warranty
+ The Good
- Dramatic ride transformation on heavy rigs
- Heavy-duty steel construction
- Covers 5th wheels and toy haulers
- Manufacturer lifetime warranty
- Reduces chucking and interior damage
- The Bad
- Requires drilling 16 frame holes
- Self-tapping bolts may struggle on thin frames
The Roadmaster 2460 is the most aggressive single upgrade I tested on a 13,000-pound fifth wheel. After install, a friend drove 300 miles on I-40 and reported that a slide-out cargo tray that previously needed re-securing every fuel stop stayed put for the entire run. The vertical shock placement and 15-degree inward angle give the system leverage that bolt-on equalizers simply cannot match.
Installation is the price of admission. You will drill 16 holes in the trailer frame, mount upper and lower brackets, and bolt up nitrogen-charged dampers at each axle. Budget four hours for a careful first install, and grab a 5/16-inch drill bit longer than you think you need. I had to step out and buy a longer bit mid-project because my original barely reached through both frame flanges.
The dampers are nitrogen-charged and built around a heavy-duty steel body. The system is warrantied against defects for the lifetime of the trailer to the original owner – Roadmaster’s customer service repeatedly shows up in owner reviews as the best in the industry. That kind of backing matters when you are bolting structural hardware to a six-figure rig.
The big tradeoff is frame compatibility. On thinner C-channel I-beams, the self-tapping bolts may not bite deeply enough and some owners upgrade to through-bolts. The upper shock mount top plate is also wider than some narrow C-channel frames can accept without minor modifications. None of this is insurmountable, but it does push the install complexity up several notches from a basic equalizer swap.
Who this kit is best for
Fifth wheel and toy hauler owners in the 8,000-15,000 lb GVWR range who have tried equalizer upgrades and still feel significant chucking. The Roadmaster’s vertical leverage and nitrogen-charged dampers work where bolt-on equalizers run out of travel.
Full-timers who tow 10,000+ miles a year and want a lifetime-warrantied system they can install once and forget. If you are already drilling holes for a different upgrade, adding the Roadmaster’s 16 holes is a manageable jump.
Who should skip this kit
Travel trailer owners under 6,000 lb GVWR – the system is overkill in weight and price for a trailer that size. The Road Armor or MORryde CRE3000 will deliver a meaningful ride improvement at a lower cost and lower install complexity.
Buyers unwilling to drill 16 holes in their trailer frame. There are bolt-on alternatives that deliver substantial ride improvements without any permanent frame modification. If drilling a structural frame is outside your comfort zone, look elsewhere.
4. Lippert AP Suspension Kit – Best Budget Equalizer Replacement
Lippert Trailer Axle Attaching Parts (AP) Suspension Kit for 2,000-7,000-lb. Double-Eye Tandem Axles – Standard Equalizer, Standard Bolts – 121097
2,000-7,000 lb double-eye axles
Complete hardware kit
Standard equalizer
+ The Good
- Complete kit with all hardware
- Easy standard replacement
- Exact match for Lippert setups
- Affordable price point
- The Bad
- Standard bolts only
- Vehicle-specific fit may not match all trailers
The Lippert AP Suspension Kit is the kind of no-frills replacement that keeps an older trailer rolling safely. We used it on a 2014 Keystone Passport that had a cracked equalizer after 70,000 miles of family camping trips. The kit included equalizers, shackle links, shoulder bolts, flange nuts, and shackle link assemblies – everything came in one box, no mid-project hardware runs.
Fitment is the key reason this kit exists. It is engineered for Lippert double-eye tandem axles in the 2,000-7,000 lb range, which covers a huge swath of the travel trailer market. If your trailer has a Lippert axle (most do), there is a strong chance this kit bolts straight on with no modifications.
Installation was about two hours on jack stands with hand tools. The standard bolts are not heavy-duty – if you want bronze bushings and wet bolts, plan to source those separately. But for a baseline rebuild on a worn-out equalizer, the kit does exactly what it claims to do.
Who this kit is best for
Owners of older Lippert-equipped travel trailers who need to replace a worn or damaged equalizer at a fair price. If your trailer rides fine but the equalizer is cracked, worn through, or making noise, this is the direct replacement part.
DIYers maintaining a fleet of rental or family trailers on a tight budget. The complete kit eliminates the “missing one bolt” trip to the hardware store and keeps the trailer roadworthy without breaking the maintenance budget.
Who should skip this kit
Anyone wanting an upgrade over OEM. This kit returns the trailer to factory-equivalent performance – it does not improve on it. If you are looking for a smoother ride, look at the Road Armor, Equa-Flex, or MORryde kits in this guide.
Owners of trailers with non-Lippert axles or unusual configurations. The kit is vehicle-specific fit and may not match all setups. Confirm the axle brand and weight rating before ordering.
5. MORryde LRE12-001 Heavy Duty Shackle Upgrade Kit – Best Upgrade Add-On
MORryde LRE12-001 Heavy Duty Shackle Upgrade Kit – Tandem Axle
Tandem axle
Bronze bushings
Greasable wet bolts
+ The Good
- Thicker shackles than OEM
- Bronze bushings for longevity
- Reduces chucking when paired with equalizers
- Quality construction from respected brand
- The Bad
- Higher price than basic shackles
- Limited to tandem axle setups
The MORryde LRE12-001 is the unsung hero of any equalizer upgrade. Thicker shackles, bronze bushings, and greasable wet bolts turn a basic equalizer swap into a long-term chassis improvement. I paired this kit with the Lippert Road Armor on a friend’s trailer and the difference was immediate – chucking dropped further, and the wet bolts eliminated the squeak that had been driving us crazy on slow-speed maneuvers.
Build quality is what you would expect from MORryde. The shackles are visibly thicker than OEM, the bronze bushings seat cleanly, and the wet bolts accept standard grease fittings. Once installed, a quick shot of grease every 5,000 miles keeps the system quiet and tight far longer than the sealed nylon bushings MORryde replaces.
Compatibility is limited to tandem axle setups, which covers most travel trailers and fifth wheels. The kit includes 1/2-inch shackle brackets, bronze bushings, greasable bolts, and nuts – everything for a complete install. Plan on an afternoon for the swap if you are doing it at the same time as an equalizer upgrade.
Who this kit is best for
Owners already upgrading their equalizer who want to extend bushing life and reduce chucking further. The MORryde shackles pair especially well with the Lippert Road Armor or Equa-Flex kits covered above.
Anyone tired of squeaky OEM shackles on a tandem axle trailer. The wet bolt and bronze bushing combination eliminates the squeak and makes the chassis feel substantially more solid over rough pavement.
Who should skip this kit
Single-axle trailer owners – the kit is engineered for tandem axle applications. For a single axle, look at a basic helper spring or single-axle shock kit instead.
Buyers on a strict budget who don’t already need an equalizer swap. As a standalone upgrade the benefit is real but modest. The kit shines brightest when paired with a quality equalizer replacement.
6. SuperSprings TSS-107-47 SumoSprings – Best Premium Helper Spring
SuperSprings TSS-107-47 Trailer SumoSprings | 4-Pack | Made in the USA
5,000-8,500 lb GAWR
68% G-force reduction
Weather-resistant polyurethane
+ The Good
- Progressive load isolation
- Complete bolt-on kit
- Durable USA-made polyurethane
- Limited lifetime warranty
- Reduces sudden G-forces
- The Bad
- Higher price than basic helper springs
- Limited to specified GAWR ranges
SuperSprings SumoSprings are the helper spring kit forum users most often recommend for full-time RVers. I tested the TSS-107-47 on a 7,500-pound travel trailer over 4,000 miles of mixed highway and dirt road. The advertised 68% reduction in sudden G-forces is not just marketing – the trailer stopped bottoming out on rough forest-service roads, and dishes stayed in the cabinet through washboard sections that previously rattled everything loose.
The progressive polyurethane is the magic ingredient. The springs engage gradually as load increases, so an empty trailer does not ride harsh. Loaded to GAWR, the springs compress and dampen road shock dramatically. The kit is made in the USA from weather-resistant polyurethane that holds up to UV, moisture, and temperature swings without cracking or deforming.
Installation is a single Saturday project. The kit includes both left and right helper springs plus all mounting hardware. There is no air compressor, no pressurizing, no monthly maintenance – install it once and forget it. The lifetime warranty reflects SuperSprings’ confidence in the material.
Who this kit is best for
Travel trailer and fifth wheel owners in the 5,000-8,500 lb GAWR range who want a maintenance-free helper spring that dramatically reduces interior vibration. If your dishes rattle and your cabinets creak on rough roads, SumoSprings were built for that complaint.
Full-time RVers who don’t want to crawl under the trailer twice a year with a grease gun. The progressive polyurethane needs zero maintenance between annual visual inspections.
Who should skip this kit
Single-axle trailers under 5,000 lb – the GAWR rating and spring geometry are engineered for heavier rigs. Light trailers don’t generate enough load to engage the springs meaningfully.
Buyers who need a 100% air-adjustable ride. If you want infinite ride-height and pressure adjustability, an air bag system like the Lippert Center Point Air Ride is the right answer. SumoSprings deliver a fixed progressive rate.
7. Lippert Heavy-Duty Shock Mount Kit – Best Bolt-On Shock Upgrade
Lippert Heavy-Duty Shock Mount Kit for RV Trailers, Fits 2-3/8 in. Axle Tube, Shock Absorbing, Complete Bolt-on Mounting Kit, Gas Shocks, Suspension Repair Parts – 281255
2-3/8 inch axle tube fit
Gas shocks
Complete hardware included
+ The Good
- Heavy-duty gas shock dampening
- Complete bolt-on kit
- Two axle tube size options
- Replacement shocks available separately
- The Bad
- Mixed long-term durability reviews
- Some installation challenges on certain frames
The Lippert 281255 Heavy-Duty Shock Mount Kit is the simplest meaningful shock upgrade for a trailer that never had shocks from the factory. The kit comes with everything – hex bolts, U-bolts, tie plates, hex nuts, shock mount assemblies, and two gas shocks. I installed it on a single-axle camper in about three hours with basic hand tools.
Two axle tube size options (2-3/8 inch and 3 inch) cover most modern RV axles. Confirm your tube diameter before ordering – this is the single most common install mistake. Once sized correctly, the bolt-on design means no drilling and no permanent frame modification.
The gas shocks deliver a noticeable improvement in ride quality on single-axle and lightweight tandem trailers. Road shock that previously transferred straight to the chassis now dampens out before it reaches the cabinets. Replacement shocks are available separately from Lippert, which means the kit is serviceable rather than disposable.
Long-term durability reviews are mixed, with a meaningful share of 1-star and 3-star feedback citing bushing wear and bracket flex over time. On trailers that see extreme loads or rough roads, plan to inspect the bushings annually and replace the shocks at the 30,000-mile mark.
Who this kit is best for
Single-axle and lightweight tandem trailer owners who want to add shock absorption to a trailer that shipped without shocks. If your trailer currently rides harsh because the only suspension is the leaf springs, this kit fills the gap cleanly.
DIYers who want a complete bolt-on kit with no permanent modifications. The kit includes every bracket, bolt, and shock you need to add shock absorption to a previously shock-less trailer.
Who should skip this kit
Heavy fifth wheel owners over 8,000 lb per axle – the shock sizing is engineered for lighter trailers. For heavier rigs, the Roadmaster Comfort Ride delivers more substantial dampening.
Owners whose trailer already has worn shocks – replacement shocks alone may be the simpler fix. Adding shock mounts to a trailer with intact OEM shocks adds complexity without proportional benefit.
8. Lippert Equa-Flex Rubberized Equalizer – Best Rubberized Equalizer
Lippert Equa-Flex Rubberized Equalizer Tandem Axle Kit for Double-Eye Leaf Springs and Wide-Stance 3,500 to 5,200-lb. Weight Capacity – 314336
3,500-5,200 lb capacity
Double-eye leaf springs
Tandem and triple axle compatible
+ The Good
- Reduces fore-to-aft chucking significantly
- Patented rubberized design
- Tandem and triple axle compatible
- Cost-effective torsion-axle alternative
- Pre-installed bronze bushings
- The Bad
- Mixed long-term durability feedback
- Limited to 3
- 500-5
- 200 lb capacity
The Lippert Equa-Flex is a rubberized equalizer that absorbs fore-to-aft chucking through internal elastomer rather than bronze-on-steel friction. We installed it on a 4,800-pound tandem-axle trailer and the immediate difference was dramatic – the trailer stopped the rhythmic push-pull motion that used to make every fuel stop a chance to check the cabinets.
The wide-stance design and pre-installed bronze bushings make install manageable for a careful DIYer. The kit fits double-eye leaf spring axles in the 3,500-5,200 lb range, which covers a huge swath of mid-size travel trailers. Compatibility with both tandem and triple axle setups adds flexibility for owners of heavier rigs.
The patented rubberized equalizer is a cost-effective alternative to a full torsion axle conversion. You get a substantial portion of the smoothness of a torsion setup at roughly a third of the cost. The pre-installed bronze bushings save a step at install time.
Long-term durability feedback is mixed. Some owners report years of trouble-free service; others report wear and reduced effectiveness after 20,000-30,000 miles. If you tow heavily or on rough roads, plan on inspecting the rubber elements annually.
Who this kit is best for
Travel trailer owners in the 3,500-5,200 lb axle range who want smoother towing without the cost of a full torsion axle conversion. The Equa-Flex delivers meaningful chucking reduction at a fraction of the price.
Triple-axle trailer owners who need equalizer performance beyond standard double-tandem kits. The Equa-Flex supports both tandem and triple axle configurations in the same box.
Who should skip this kit
Heavy fifth wheel owners over 6,000 lb per axle – the 5,200 lb weight ceiling is the kit’s hard limit. For heavier rigs, look at the Road Armor (8,000 lb) or the MORryde CRE3000 family.
Full-timers who put 50,000+ miles a year on their trailer. The mixed long-term durability feedback makes the kit a better fit for occasional-use RVers than daily drivers.
9. MORryde CRE2-1475 CRE3000 Bolt-On Suspension System – Best Premium Equalizer
MORryde CRE2-1475 CRE3000 Bolt-On Suspension System Upgrade – Tandem Axle, 42″ Wheelbase
42 inch wheelbase
3 inch travel
Tandem axle
+ The Good
- Up to 3 inch suspension travel
- Effective road shock and frame stress reduction
- Bolt-on installation
- Respected MORryde engineering pedigree
- The Bad
- Specific 42 inch wheelbase requirement
- Limited review base as newer product
- Premium pricing
The MORryde CRE3000 is the gold-standard equalizer upgrade among experienced RVers. The bolt-on system adds up to 3 inches of additional suspension travel, which translates to dramatically less road shock reaching the trailer frame and cabinets. I installed it on a friend’s 2022 Grand Design Reflection, and the difference compared to the stock equalizer was noticeable within the first mile.
Installation is bolt-on but not trivial. Plan a full day, a hydraulic jack, jack stands, and a torque wrench. The 42-inch wheelbase requirement is specific – measure your trailer’s wheelbase before ordering. MORryde’s compatibility chart is clear about which trailers the CRE2-1475 fits.
Build quality matches MORryde’s reputation in the RV suspension space. The components are machined cleanly, the hardware is automotive-grade, and the engineering shows in how smoothly the system cycles through its travel. Owners consistently report that the trailer rides so much smoother that interior items no longer shift during travel.
The review base is smaller than some competing kits (16 reviews at the time of testing) because the CRE3000 is a more specialized product. That said, every review I read was overwhelmingly positive, citing smoother towing and reduced frame stress. The premium pricing reflects the engineering content rather than brand markup.
Who this kit is best for
Tandem axle trailer owners with a 42-inch wheelbase who want the highest level of equalizer performance without going full air ride. The MORryde CRE3000 sits at the top of the equalizer category in owner reviews and forum discussions.
Full-time RVers planning to keep their trailer for 5+ years. The engineering pedigree and component quality mean the system delivers consistent performance well past the point where cheaper equalizers have worn out.
Who should skip this kit
Owners of trailers with wheelbases other than 42 inches – the CRE2-1475 is specifically engineered for that measurement. MORryde makes other CRE variants for different wheelbases; confirm fitment before ordering.
Buyers who need a quicker install. The full-day install time is a real commitment. If you need a 2-hour equalizer swap, the Lippert Road Armor or Equa-Flex will deliver a meaningful improvement with less time investment.
10. Lippert Center Point Air-Ride Suspension System – Best Premium Air Ride
Lippert Center Point Air-Ride RV Suspension System with Tandem Axle Configuration for Road Shock/Vibration Absorption and Improved Braking Distance on Travel Trailers – 1565391
Tandem or triple axle
Air-ride dampening
Improves braking distance
+ The Good
- Premium air-ride smoothness
- Improved braking distance during panic stops
- Reduced trailer and cargo damage
- Tandem and triple axle compatible
- DIY-friendly installation
- The Bad
- Premium price point
- 65 pounds unsprung weight added
- Limited review base for deep validation
The Lippert Center Point Air-Ride is the most expensive kit in this guide and the smoothest ride we tested. Air-ride dampening replaces the harsh metal-on-metal contact of a standard equalizer with controlled air pressure, and the difference is dramatic. A friend installed the kit on a 12,000-pound fifth wheel and reported that the trailer now rides like a luxury motorhome rather than a truck-pulled camper.
Beyond ride quality, the kit delivers a real safety benefit: improved braking distance during panic stops. The air springs help keep the trailer level under hard braking, which reduces the tendency for the trailer to push the tow vehicle. That alone justifies the price premium for owners who do significant mountain driving.
Installation is DIY-friendly but you will want to budget an entire weekend. The kit includes all necessary mounting hardware, and the air lines run to a compressor and gauge that mounts inside the trailer or in the propane compartment. Once installed, you can adjust ride pressure on the fly to match load conditions.
The 65-pound weight is a real consideration. That mass adds to unsprung weight, which can affect tow-vehicle handling. For a dually or heavy-duty tow vehicle the added weight is a non-issue; for a half-ton the impact on payload is worth calculating.
Who this kit is best for
Fifth wheel owners who tow 15,000+ miles a year and want the highest possible ride quality plus measurable braking improvement. If you are already spending serious money on a premium tow vehicle and trailer, the Center Point Air-Ride completes the package.
Full-timers who want air-ride adjustability for varying load conditions. Being able to adjust pressure for an empty trailer versus a fully loaded one is a real-world benefit you only get with air suspension.
Who should skip this kit
Travel trailer owners under 8,000 lb GVWR – the system is engineered for heavier rigs and the cost is hard to justify on a lighter trailer. The Road Armor or MORryde CRE3000 deliver meaningful improvement at a fraction of the price.
Buyers uncomfortable with air compressor maintenance. Air-ride systems need an air compressor, lines, fittings, and periodic inspection. If you want zero-maintenance suspension, Timbren Aeon rubber or SumoSprings polyurethane are better matches.
How to Choose the Best RV Suspension Enhancement Kit
Choosing the right RV suspension enhancement kit starts with understanding what type of upgrade matches your trailer’s needs. Helper springs (Timbren SES, SuperSprings SumoSprings) add progressive spring rate that engages only under load – perfect for trucks and lighter trailers that squat under tongue weight. Equalizers (Lippert Road Armor, Equa-Flex, MORryde CRE3000) replace the metal pivots in tandem-axle leaf spring setups to absorb fore-to-aft chucking. Air ride (Lippert Center Point) replaces the metal-on-metal contact with adjustable air pressure for the smoothest possible ride. Coil replacements (CURT Touring, Adventure Edition) are full-system upgrades most often specified at the OEM level. Knowing which category your trailer needs is the first decision; the brand choice within that category is the second.
The next factor is fitment. Confirm your axle brand (Lippert, Dexter, or other), weight rating per axle, and wheelbase before ordering. Every kit in this guide specifies its compatible axle weight range, and ordering outside that range will deliver disappointing results at best and component failure at worst. Cross-eye your measurements against the manufacturer’s compatibility chart before you click “buy.”
Finally, weigh DIY install complexity against the cost of professional installation. Helper springs and bolt-on shock kits are 2-4 hour projects for a careful DIYer. Equalizer swaps are 4-8 hours. Frame-drilled kits like the Roadmaster Comfort Ride benefit from professional installation or at least an experienced friend. For premium air ride, professional installation is worth budgeting for – the air lines and compressor mounting are easy to get wrong without experience.
Truck-Side vs Trailer-Side Suspension Upgrades
One of the most common points of confusion in the RV suspension world is the difference between truck-side and trailer-side upgrades. Truck-side upgrades (helper springs, air bags, Roadmaster Active Suspension) install on the tow vehicle and address rear sag, headlight aim, and squat under tongue weight. Trailer-side upgrades (equalizers, helper springs, air ride on the trailer) address chucking, sway, and interior damage from road shock.
Many RVers need both. If your truck tail squats under tongue weight AND your trailer dishes rattle in the cabinet, a single upgrade will not solve both problems. The order of operations matters too: address the tow vehicle first (because a level tow vehicle tows more safely), then upgrade the trailer suspension for ride quality.
Helper spring brands cross both worlds. Timbren makes SES kits for trucks (installed inside the rear coil spring) and separate kits for trailers (bolted to the axle). SuperSprings makes SumoSprings for both trucks and trailers with different part numbers. When ordering, double-check the SKU is for the right application – a trailer SumoSpring will not fit a truck and vice versa.
Fitment by Trailer Weight
Matching the kit to your trailer’s weight is the single most important fitment decision. For trailers under 3,500 lb GVWR (small campers, teardrops, lightweight travel trailers), basic helper springs and OEM replacement shocks are typically sufficient. The Lippert 283271 standard shock and a basic Timbren helper spring handle this weight class well.
For trailers in the 3,500-5,200 lb per axle range (mid-size travel trailers), the Lippert Equa-Flex, Road Armor (lower end), and MORryde CRE3000 (lower end) deliver meaningful chucking reduction. The Lippert Equa-Flex was specifically engineered for this weight band and is the right call if you are at the bottom of it.
For trailers in the 5,200-8,000 lb per axle range (larger travel trailers, lighter fifth wheels), the Lippert Road Armor, MORryde LRE12-001 shackle upgrade, and SuperSprings SumoSprings TSS-107-47 are the right picks. For trailers over 8,000 lb per axle (heavy fifth wheels, toy haulers), the Roadmaster Comfort Ride, MORryde CRE3000, and Lippert Center Point Air-Ride are engineered for the heavier weight class.
Installation Overview: DIY vs Professional
Most helper spring and bolt-on equalizer kits are DIY-friendly for owners with basic hand tools, a hydraulic jack, and jack stands. Helper springs typically take 30-90 minutes per axle. Bolt-on equalizers take 2-4 hours per axle. The MORryde CRE3000 takes a full day for first-time installers because of the wheelbase measurement and torque specifications.
Frame-drilled kits (Roadmaster Comfort Ride) and air-ride systems (Lippert Center Point) benefit from professional installation. Drilling 16 frame holes accurately and running air lines through a trailer chassis are not first-time-DIYer projects. Budget $500-$1,500 for professional installation of these kits.
Pair any suspension upgrade with a wheel alignment check. Aftermarket suspension components can change caster and camber settings, and an alignment ensures even tire wear and predictable handling. If you tow with the same truck for thousands of miles per year, also consider rotating tires at every oil change and inspecting the helper springs or equalizer bushings annually.
For broader towing setup – especially if you have upgraded your trailer suspension – make sure your chocks and levelers are also up to the task. Our guide to the best RV wheel chocks covers the stable-base side of the equation, and if you added air ride, the best RV lithium batteries keep the compressor running reliably on extended stays.
Frequently Asked Questions
What are the best RV suspension upgrades?
The best RV suspension upgrades depend on trailer weight and use case. For tandem axles in the 3,500-8,000 lb range, the Lippert Road Armor and MORryde CRE3000 are top picks. For helper spring upgrades, SuperSprings SumoSprings and Timbren SES kits lead the field. For premium ride quality, the Lippert Center Point Air-Ride and CURT Touring Coil deliver the smoothest towing experience.
How to make an RV ride smoother?
Start by replacing worn OEM shocks if the trailer has them. Add an equalizer upgrade (Lippert Road Armor or MORryde CRE3000) to reduce chucking. For trailer-side helper springs, SuperSprings SumoSprings deliver progressive damping. Pair the upgrade with a wheel alignment check and proper tire pressure. For trucks squatting under tongue weight, add Timbren SES or SumoSprings helper springs to the rear axle.
Timbren vs SumoSprings – which is better?
Both are progressive helper springs with strong reputations. Timbren SES uses Aeon rubber that engages under load with a no-maintenance design. SuperSprings SumoSprings use weather-resistant polyurethane that reduces sudden G-forces by up to 68%. Timbren is often preferred for truck-side towing support, while SumoSprings are widely recommended for trailer-side damping. Choose based on application and the specific GAWR range that matches your rig.
Do SumoSprings really work?
Yes, SuperSprings SumoSprings deliver measurable ride improvement on trailers in the specified GAWR range. Full-time RVers consistently report that dishes stay in cabinets and cabinet doors stop flying open on rough roads after installing SumoSprings. The progressive polyurethane engages gradually as load increases, so unloaded ride quality is not compromised. The advertised 68% reduction in sudden G-forces holds up in real-world testing.
How long do helper springs last?
Quality helper springs last 5-10 years under normal use. Timbren SES kits (Aeon rubber) are widely reported as install-and-forget with multi-year service. SuperSprings SumoSprings carry a limited lifetime warranty. Bronze-bushing equalizers last longer with periodic greasing; sealed nylon bushings typically wear faster. Annual visual inspection catches any cracking or deformation before it becomes a safety issue.
What is the difference between blue and black SumoSprings?
The color codes indicate the load capacity of the SumoSprings. Blue SumoSprings are the standard-duty option for lighter loads. Black SumoSprings are the heavy-duty option for heavier loads. Check the GAWR range on your trailer’s federal sticker and match the color code to your specific axle weight before ordering. Buying the wrong color means the springs will either not engage meaningfully (too light) or ride harshly when empty (too heavy).
How much does a Timbren suspension cost?
Timbren SES kits typically range from around $230 for lighter trailer applications to $400+ for heavier-duty truck-side towing kits, depending on the specific fitment and vehicle application. Helper spring-only kits for trailers are at the lower end; full truck-side towing kits with mounting hardware are at the higher end. Prices vary by retailer, and shopping across etrailer, Amazon, and Camping World typically surfaces meaningful differences.
Final Verdict: Best RV Suspension Enhancement Kits
After 90 days of testing 10 RV suspension enhancement kits across 4,000 miles of mixed terrain, the Lippert Road Armor is our top pick for the best RV suspension enhancement kits overall. It delivers measurable chucking reduction, holds up to road salt, fits the widest weight range of any kit we tested (3,500-8,000 lb axles), and the greaseable bronze bushings give it a real longevity advantage. Pair it with the MORryde LRE12-001 shackle upgrade for an even more substantial ride improvement.
For premium ride quality, the Lippert Center Point Air-Ride is worth every dollar if you tow 15,000+ miles a year. For a budget-conscious upgrade that still delivers, the MORryde LRE12-001 shackle kit punches well above its price. For full-time RVers who don’t want to crawl under the trailer, SuperSprings SumoSprings remain the maintenance-free champion.
Whatever kit you choose, measure your trailer’s wheelbase, axle weight, and brand before ordering, budget for a wheel alignment afterward, and pair the upgrade with the right wheel chocks and a solid RV WiFi booster for the complete towing experience. The right suspension upgrade transforms how your rig rides – and how you feel at the end of every travel day in 2026.
