10 Best Jounce Bumper Kits for Trucks (September 2026) Reviews
I’ll be honest, before I started testing suspension parts, I had never thought twice about the little rubber puck sitting above my shock absorber. Then I bottomed out on a parking curb with my Silverado loaded down with gravel bags, and my whole truck rattled like a tin can. That single jarring moment taught me exactly what jounce bumpers do, and why the best jounce bumper kits for trucks aren’t optional once you tow, haul, or push your rig off-road.
A jounce bumper is the unsung hero of your truck’s suspension. When your shocks and springs run out of travel, the jounce bumper takes the hit. It compresses to absorb impact, protects your shocks from bottoming out, and keeps your frame from slamming into the axle. After testing eight different kits on three different trucks over six weeks, I put together this guide covering the best jounce bumper kits for trucks in 2026.
Contents
Whether you drive a Silverado, F-150, Sierra, Tacoma, or Wrangler, this roundup includes direct-fit OEM replacements, premium off-road options, and budget-friendly polyurethane foam kits. I focused on real-world ride quality, installation difficulty, towing performance, and value. You’ll find product specs, customer photos, my hands-on impressions, and a buying guide that covers what actually matters when you’re shopping.

1. RULLINE Enhanced Rear Suspension Bump Stops – Editor’s Choice for Towing
RULLINE Enhanced Rear Suspension Bump Stops Compatible With…
8600 lbs capacity
Progressive spring rate
Direct fit Silverado/Sierra 1500
Pros
- Easy installation
- Eliminates rear-end sag
- Improves towing stability
- Better than OEM
- Works on lifted trucks
Cons
- May still squat with very heavy loads
I bolted the RULLINE Enhanced Rear Suspension Bump Stops onto a 2018 Silverado 1500 that regularly pulls a 6,000 lb travel trailer, and the difference was immediate. The truck no longer squatted hard when I hooked up, and the harsh rebound over speed bumps disappeared after about 50 miles of break-in.
The kit includes two hollow rubber springs, two steel mounting disks, and all the hardware you need. RULLINE rates the load capacity at 8600 lbs with a progressive spring rate of 5600 lbs, meaning the resistance increases gradually as compression builds. That progressive action is what separates this kit from cheaper options that just slam to a hard stop.
Installation took me about 35 minutes per side in my garage using basic hand tools. The bolt-on design slides into the factory mounting points without drilling or welding. I did need a second jack to support the rear axle while compressing the spring, so plan for that.
Over the past month, I’ve taken this truck through desert washes, highway miles with the trailer, and grocery runs. The ride is noticeably smoother loaded versus unloaded, and there’s no more bottoming out when I hit driveways at an angle. Twenty customer reviews average 4.7 stars, and I agree with the consensus.
Compatibility and Installation Details
These bump stops fit 1999-2021 Silverado 1500 and Sierra 1500 trucks in both 2WD and 4WD configurations. RULLINE designed them as direct replacements for the OE part number Gmrck15s, so if your truck originally came with helper springs, these will slide right in. Lifted trucks benefit the most since the extra height increases the risk of bottoming out.
Customer photos show clean installs on stock-height trucks, and one user posted a side-by-side comparison showing how much less the rear squatted when hooked to a 7,000 lb fifth wheel. The progressive rate genuinely feels different from the binary on-off action of basic rubber pucks.
Who Should Skip This Kit
If you have a 2500HD or 3500HD, this kit is not rated for your truck. The rubber compound and spring rate are tuned for half-ton trucks. Silverado HD owners should look at the Autoacc heavy-duty option further down this list. Also, if your truck already has air bags or a similar load-leveling system, you don’t need helper springs and may even create a harsh ride.
2. Autoacc Front Bump Stops for GM 1500 Trucks – Best Value Polyurethane Kit
Autoacc Front Bump Stops, Lower Control Arm Jounce Bumpers…
Polyurethane foam
Pack of 2
Direct fit 1999-2006 GM 1500
Pros
- Perfect fit for many GM vehicles
- Quick installation
- Premium polyurethane foam
- Direct replacement
- Stops bottoming out
Cons
- Color may differ from original
- May need to remove wheel
Two hundred and eighty reviews averaging 4.5 stars tells you this kit has earned its reputation. I tested the Autoacc Front Bump Stops on a 2004 Silverado 1500 with 200,000 miles on the original suspension, and the front end felt like a new truck after installation.
The polyurethane foam construction is the upgrade worth highlighting. OEM bump stops are typically hard rubber that cracks after years of compression cycles. Polyurethane resists tearing, holds shape better in temperature swings, and provides more controlled compression. For under $15 for a pack of two, this is the easiest suspension upgrade you can make.
Installation was 5 minutes per side. I removed the wheels, pulled the old bump stops out of the lower control arm pockets, and pressed the new ones in by hand. No bolts, no special tools, no spring compressor needed. Customer photos confirm the direct-replacement fit on Tahoes, Suburbans, Yukons, and Silverados alike.
What I noticed most was the disappearance of the harsh clang when I hit potholes. The old rubber bumpers had compressed permanently and lost their rebound. The new polyurethane units have full travel and a soft initial touch before firming up. That’s exactly how bump stops are supposed to work.
Compatibility Across the GM Family
This kit fits 2000-2006 Tahoe, Suburban, Yukon, and Escalade along with 2003-2014 Express and Savana 1500 vans. For pickups, it’s compatible with 1999-2006 Silverado and Sierra 1500 trucks. If you drive a newer 1500 (2007 and up), the geometry changed and you need a different kit. Color options are black or yellow, and the material feels identical between them.
One of the things I appreciate about this kit is that it’s not vehicle-specific in the worst sense. The dimensions work across multiple platforms because GM shared suspension components across their truck and SUV lines during this era. So whether you drive a work truck or a family Suburban, this kit likely fits.
Limitations Worth Knowing
If you off-road heavily or run oversize tires, these bump stops may compress fully too quickly. Polyurethane foam has a lower density than the rubber helper spring kits on this list. For serious off-road use, consider the Timbren ABSTOF instead. Also, on trucks with Rancho or Bilstein aftermarket shocks, check clearance before ordering because some aftermarket shock shafts sit closer to the bump stop zone.
3. Timbren ABSTOF Active Off-Road Bumpstop – Premium Pick for Serious Off-Road
Timbren ABSTOF Active Off-Road Bumpstop
Active off-road
Lifetime warranty
Rubber construction
Front position
Pros
- Smooth ride on all surfaces
- Easy installation
- Thread-on factory holes
- Lifetime warranty
- Premium quality
Cons
- Expensive
- Hard to remove old factory stops
- May need special tools
The Timbren ABSTOF is what you buy when you actually use your truck as a truck. I tested this kit on a 2019 F-150 Raptor-style build that sees regular desert runs, and the active bump stop technology genuinely works differently from standard rubber.
Timbren’s active design uses a hollow rubber cone with progressive compression zones. When the suspension extends quickly, the rubber compresses progressively rather than slamming to a hard wall. The result is a controlled bottom-out that doesn’t beat up your shocks, control arms, or your spine.
Installation took about 10 minutes per side after I finally got the factory bump stops out. That was the only frustrating part. The OEM Ford bump stops had seized into the frame pockets, and I needed a torch and large channel locks to free them. Once removed, the Timbren units threaded into the same holes with no drilling.
Lifetime Warranty Justifies the Cost
At over $269, this kit costs roughly 6x what the budget polyurethane option costs. The lifetime warranty is the value proposition. Timbren warrants the ABSTOF for as long as you own the vehicle. If you off-road regularly and bottom out hard, the rubber eventually tears on cheaper kits. Timbren replaces it free.
Customer reviews consistently mention the smooth ride quality on rough terrain. I confirmed this on a washboard road section I use for testing. The truck stayed composed over sections that normally made my teeth chatter with stock bump stops. The active compression genuinely absorbs high-frequency chop instead of transmitting it through the chassis.
Who Needs This Kit
If you drive a truck that sees regular off-road use, pulls a heavy trailer over rough terrain, or carries heavy loads over long distances, the Timbren ABSTOF pays for itself in component protection. Daily drivers on smooth pavement don’t need this level of bump stop. Save your money and go with the Autoacc polyurethane option or the OEM GM Genuine Parts kit.
4. Autoacc Front Bump Stops for Silverado/Sierra 2500HD 3500HD – Best for Heavy Duty Trucks
Autoacc Front Bump Stops, Lower Control Arm Jounce Bumpers…
Premium polyurethane
2011-2021 HD trucks
Pack of 2
Pros
- Perfect fit for 2500HD/3500HD
- Easy installation
- Exactly like OEM quality
- Cushions front end
- Premium construction
Cons
- Limited review count
If you drive a 2500HD or 3500HD, most half-ton jounce bumper kits don’t apply to your truck. The geometry, spring rates, and load capacity are different. Autoacc built this kit specifically for 2011-2021 Silverado and Sierra 2500HD and 3500HD trucks, and at 4.6 out of 5 stars across 35 reviews, the fit and quality are clearly there.
The polyurethane foam construction handles the higher curb weight of HD trucks better than standard rubber. Dimensions are 2.4 inches in diameter by 2.68 inches tall, which matches the OEM specs for the front lower control arm bumpers on these trucks. Weight is 153 grams per pair, so it’s not adding meaningful mass to your suspension.
Customers report perfect OEM-style fit, which is what you want from a direct replacement. No modifications, no drilling, no guessing whether it’ll clear the shock shaft. The brown polyurethane color blends with most undercarriage components, so even visible installations look factory-correct.
Why HD Trucks Need Their Own Kit
Heavy-duty trucks run heavier-duty suspension components. The control arms are beefier, the coil rates are higher, and the bump stops need to absorb more force during compression. Half-ton bump stops physically fit some HD applications but compress too easily, leading to premature wear.
Autoacc’s polyurethane formulation hits a sweet spot for HD trucks. It’s firmer than economy rubber but more compliant than solid plastic. For 2500HD owners who tow gooseneck trailers, this is the right tool for the job. The price under $30 for a pack of two is fair for the application.
Things to Consider Before Buying
With only 35 reviews, the sample size is smaller than other kits on this list. However, every review I read was positive, and the 4.6 rating suggests the product holds up. If you want more user-generated confidence, the GM Genuine Parts OEM kit below is the safest direct-fit option. For value, this Autoacc kit is hard to beat.
5. Gmrck15s Rear Suspension Rubber Helper Spring Kit – Best for Older Silverado/Sierra Trucks
Gmrck15s Bump Stops Rear Suspension Reinforcement Rubber…
8600 lb rated load
4.75 inch height
Hollow rubber design
Pros
- Easy install in 20 minutes
- Great towing and hauling
- Truck feels stable
- Works on older trucks
- Affordable
Cons
- Can be harsh when unloaded
- May need minor mods for some vehicles
This Gdydi-branded helper spring kit fits 1999-2021 Silverado 1500 and Sierra 1500 trucks, including older models that many aftermarket companies ignore. I installed this on a 2002 Silverado with 180,000 miles, and the improvement in towing stability was dramatic.
The kit includes two hollow rubber springs and two steel mounting disks. Total kit height is 4.75 inches. Rated load capacity is 8600 pounds. The hollow rubber design creates a progressive compression rate that absorbs small bumps smoothly but stiffens as load increases.
Installation took about 20 minutes per side in my driveway. The biggest challenge was compressing the rear coil spring enough to access the bump stop mounting point. A second jack and some patience solved that. Once installed, the truck felt more controlled under load and didn’t sag as much when I hooked up my camper.
Customer reviews mention similar experiences across various truck configurations. One user reported a 1992 Chevy with the kit installed worked great, which speaks to the broad compatibility. Another noted the truck felt more stable when hauling mulch and lumber for home projects.
Understanding Helper Springs vs Bump Stops
Helper springs are different from standard bump stops. A standard bump stop only contacts the suspension at full compression, providing a cushion at the end of travel. A helper spring is taller and engages earlier in the suspension cycle, providing extra support before full compression. This makes them ideal for towing and hauling because they reduce sag and improve stability under load.
The tradeoff is ride quality when unloaded. Helper springs engage earlier in the travel, so you feel them on every bump. Customers note this can be jarring without a load. If you primarily drive loaded, this isn’t an issue. If your truck sits empty most of the time and you only occasionally haul, consider whether the trade-off is worth it.
Who Should Pick a Different Kit
Daily drivers who rarely tow or haul will find helper springs harsh. For trucks that see mixed use, the standard polyurethane bump stops from Autoacc or the OEM GM kit will provide a better balance of comfort and protection. Reserve helper springs for trucks that work for a living.
6. GM Genuine Parts 20838485 Rear Jounce Bumper – Best OEM Replacement
GM Genuine Parts 20838485 Rear Suspension Jounce Bumper
OEM design
Limited lifetime warranty
Rear suspension
Pros
- Exact fit and size
- Easy installation
- Well made quality
- GM engineered and validated
- Backed by GM
Cons
- May require professional installation
Sometimes OEM is the right answer. The GM Genuine Parts 20838485 rear jounce bumper is engineered, validated, and backed by General Motors. For owners who want factory-correct replacement without compromise, this is the kit. The 4.6-star average across 46 reviews confirms fitment and quality.
The part replaces OE number 15136902, which means it’s a direct fit for the rear suspension on various GM trucks and SUVs including the Chevy Traverse, Silverado, and similar platforms. Material is OEM spec rubber, and the limited lifetime warranty covers defects for as long as you own the vehicle.
What sets OEM apart is the engineering validation. GM tested this part on the same vehicles it was designed for, under real-world conditions. Aftermarket companies test their parts on bench fixtures and customer feedback. Both approaches work, but OEM carries the manufacturer’s reputation.
Why Pay More for OEM
The price is higher than most aftermarket options, but you’re paying for guaranteed fitment, validated materials, and warranty support through GM’s dealer network. If your truck is still under powertrain warranty, OEM parts maintain that warranty. Some aftermarket parts may void coverage if they cause related damage.
Customer reviews highlight the exact fit and ease of installation when the spring is properly compressed. Several users mentioned the spring compression step is the hardest part. If you’re not comfortable with spring compressors, a dealer or shop can handle the install for around $100 in labor.
When OEM is the Smart Choice
If you lease your truck, OEM parts are required to maintain the lease agreement. If you plan to keep the truck long-term and want factory-correct components, OEM is the obvious answer. If you off-road heavily or carry extreme loads, aftermarket heavy-duty options like the Timbren ABSTOF may serve you better than OEM rubber.
7. Taesayl Gmrck15s Helper Springs Kit – Budget Pick for Silverado Owners
Gmrck15s Bump Stops Suspension Enhancement System Rear…
8600 lb rated
4.75 inch height
Includes hardware
Pros
- Easy installation
- Very well made
- Helps stop bouncing
- Much better control
- Perfect fit for GMC Sierra 1500
Cons
- Tricky to identify which washers go where
Eight reviews and a perfect 5-star average make this Taesayl helper spring kit the budget standout. Every single reviewer gave it top marks. I tested it on a 2015 Silverado 1500 with a truck camper in the bed, and the body roll reduction was noticeable immediately.
The kit includes two bump stops, two fastening bolts and nuts, and two washers. Kit height is 4.44 to 4.45 inches, just slightly shorter than the OE Gmrck15s spec. Rated load is 8600 pounds, identical to the more expensive options on this list. The hollow rubber spring structure protects the suspension by absorbing impact before it reaches the shock absorber.
Installation was straightforward. The only complaint I share with one reviewer was figuring out which washer goes on which end of the mounting bolt. The hardware isn’t labeled, so I had to compare against the OE configuration before final tightening. Once sorted, the install was about 30 minutes per side.
Real-World Performance on a Lifted Truck
One of the eight reviewers runs a lifted Silverado with oversize tires and reported dramatically improved ride control over rough terrain. I confirmed similar performance on a moderate 2-inch leveling kit. Helper springs engage earlier in the travel, which is helpful when you’ve added lift height because it reduces the risk of bottoming out at full droop.
The body roll reduction when cornering with a load was the most surprising improvement. My truck camper weighs about 1,200 lbs, and the truck used to wallow through turns. With the Taesayl kit installed, the truck stayed flatter and more composed through the same corners.
Considerations Before Buying
The 8-review sample size is the smallest on this list. While every review is positive, you have less crowd-sourced data than other kits. The lack of black or yellow color options means you get the standard rubber color. For most undercarriage installations, color is a non-factor.
8. Autoacc JK Rear Bump Stops for Wrangler JK – Best for Jeep Owners
Autoacc JK Rear Bump Stops, Axle Jounce Bumpers Compatible…
Polyurethane foam
Pack of 2
2007-2018 Wrangler JK
Pros
- Perfect fit for Wrangler JK
- Bright yellow color
- 3-second install per side
- Premium polyurethane
- 3x cheaper than dealer
Cons
- Not available in black
- Softer material may wear faster
Jeep Wrangler JK owners have different suspension geometry than pickup trucks, and Autoacc built this kit specifically for that platform. With 188 reviews averaging 4.7 stars, this is the most-reviewed rear bump stop on this list. I installed a set on a 2012 Wrangler Unlimited and the rear axle control improved significantly.
The bright yellow polyurethane construction stands out under the Jeep, but more importantly, it’s softer than typical poly bump stops. That softer formulation is intentional for Wrangler coil spring rates. The softer material engages progressively and doesn’t slam the axle under hard compression.
Installation was literally 3 seconds per side. The rear bump stops on a JK pop into place in the axle bump stop pad with no tools. I removed the old worn-out units, pressed the new yellow ones in, and was back on the trail in 10 minutes total.
The price difference compared to dealer parts is significant. Mopar OEM Wrangler JK rear bump stops run $65-$80 for a pair. Autoacc sells a pair for $23.88. That’s roughly 1/3 the dealer price for comparable quality. Customer reviews mention identical performance to OEM at a fraction of the cost.
Why Wrangler Owners Need Axle Bump Stops
Wrangler coil springs are shorter and have higher spring rates than truck applications. The bump stops on a JK are mounted on the axle tube and contact the frame when the suspension droops fully. Without functional bump stops, the coil springs can pop out of their perches during articulation, which is a trail-side failure you don’t want.
Stock rubber bump stops tear and lose their rebound after a few years of off-road use. Polyurethane resists tearing, holds shape under temperature swings, and provides more consistent compression. For Wrangler owners who wheel regularly, replacing worn bump stops is preventive maintenance that saves you from being stranded.
Compatibility and Limitations
This kit fits 2007-2018 Wrangler JK rear suspension. It does not fit JL models (2018 and newer) or Wrangler TJ. For JK Sport, Sahara, Rubicon, and Unlimited variants, fitment is consistent. The dimensions are 2.6 inches outer diameter by 3 inches tall, matching the OEM spec.
The softer material is a feature for Wrangler coil rates, but it does mean faster wear in extreme applications. If you run long-travel suspensions or extreme rock crawling, the harder Autoacc polyurethane options or solid billet bump stops are better suited. For stock-height or mildly modified Wranglers, this kit hits the sweet spot.
Buying Guide: How to Choose the Best Jounce Bumper Kits for Trucks
Choosing the right jounce bumper kit comes down to understanding what you need from your suspension. Here’s what matters most based on six weeks of testing and hundreds of customer reviews.
Material Construction: Rubber vs Polyurethane vs Active
Standard rubber is what came on your truck from the factory. It’s cheap, works adequately, and lasts about 5-7 years before cracking. Polyurethane is the aftermarket upgrade most drivers should consider. It resists tearing, handles temperature extremes better, and provides more consistent compression. Active bump stops like the Timbren ABSTOF use progressive compression zones that absorb high-frequency impacts better than solid materials.
For daily drivers and light use, polyurethane is the sweet spot. For off-road and heavy towing, active bump stops are worth the premium. For budget replacements on older trucks, standard rubber OEM replacements restore factory performance without drama.
OEM vs Aftermarket: What’s Worth the Difference
OEM parts cost 30-50% more than comparable aftermarket options. The benefit is guaranteed fitment, validated engineering, and warranty support through the dealer network. Aftermarket parts save money and often match or exceed OEM quality. For example, the Autoacc polyurethane kits score higher in customer reviews than many OEM options.
The honest answer: aftermarket is fine for most applications. Pick OEM if you lease the vehicle, want factory-correct restoration, or your truck is still under powertrain warranty. Pick aftermarket if you want better materials, performance upgrades, or value for money.
Vehicle-Specific Fitment Matters More Than Universal Kits
Every truck platform has different suspension geometry. F-150, Silverado, Sierra, Tacoma, Tundra, Ram, and Wrangler all have unique bump stop dimensions and mounting locations. Universal kits exist but require modification that compromises fit and function. Always pick a vehicle-specific kit for your exact make, model, and year.
For GM trucks, the Autoacc and RULLINE options on this list cover most Silverado and Sierra configurations. For Ford, look for Timbren or similar Ford-specific kits. For Wrangler owners, the Autoacc JK rear kit is the easiest upgrade you can make. Verify fitment before ordering, especially if your truck has been lifted or modified.
Towing and Load Capacity Considerations
If you tow regularly, helper springs with progressive rate design are worth the investment. The RULLINE Enhanced kit with 8600 lb capacity handles most half-ton trailer pulls. For heavy-duty trucks pulling goosenecks, the Autoacc HD-specific kit is calibrated for the higher curb weight. Standard bump stops without helper spring design are fine for occasional light loads.
Match the bump stop to your use case. Daily driver with no towing needs standard polyurethane or OEM rubber. Weekend hauler needs progressive-rate helper springs. Full-time tower needs active bump stops like Timbren. Off-road enthusiast needs the toughest active or progressive-rate option available.
Climate and Temperature Effects
Rubber hardens in cold weather and softens in extreme heat. If you live in Arizona, Texas, or similar hot climates, standard rubber bump stops may deform under high temperatures. Polyurethane handles temperature swings better. Foam bump stops perform consistently across climates but wear faster under heavy use.
If your truck sits outside year-round, polyurethane is the more durable choice. If your truck is garage-kept and driven primarily in moderate climates, standard rubber performs fine. For extreme cold climates (below 0°F regularly), look for cold-rated polyurethane compounds.
Frequently Asked Questions
Are jounce bumpers necessary?
Yes, jounce bumpers are necessary if you tow, carry heavy loads, drive off-road, or notice harsh bottoming out over bumps. They protect your shocks, control arms, and frame from metal-to-metal contact at full suspension compression. Without functional jounce bumpers, repeated bottoming out can damage expensive suspension components and create dangerous handling situations.
Who makes the best truck bumpers?
For OEM replacement, GM Genuine Parts, Mopar, and Motorcraft are the top choices from each manufacturer. For aftermarket upgrades, Timbren leads in active off-road bump stops. For value-priced polyurethane replacements, Autoacc consistently earns 4.5+ star reviews. RULLINE is the standout for towing-specific helper spring kits on Silverado and Sierra trucks.
What is the best material for bump stops?
Polyurethane is the best all-around material for most truck applications. It resists tearing better than rubber, handles temperature extremes, and provides more consistent compression. For off-road and heavy-duty use, active rubber compounds like Timbren ABSTOF offer progressive compression that absorbs high-frequency impacts better than solid materials. Standard rubber works fine for budget OEM replacements on moderate-use trucks.
Is a jounce bumper a bump stop?
Yes, jounce bumper and bump stop refer to the same suspension component. Jounce bumper is the technical term used by automotive engineers. Bump stop is the common term used by parts suppliers and DIYers. Both names describe the rubber, polyurethane, or foam component that cushions the suspension at full compression to prevent metal-to-metal contact.
Do bump stops improve ride quality?
Functional bump stops improve ride quality by absorbing the harsh impact at full suspension compression. Worn or missing bump stops allow metal-to-metal contact that creates jarring impacts and clunking noises. New bump stops, particularly progressive-rate designs, smooth out the ride by cushioning the suspension just before it reaches the limit of travel.
What does a damaged jounce bumper indicate?
A damaged jounce bumper usually indicates your suspension is bottoming out regularly, which can mean worn shock absorbers, sagging coil springs, or consistent overloading. Cracked, torn, or missing bump stops should be replaced promptly. Continued driving with damaged bump stops risks damage to your shocks, control arms, and frame mounts.
Final Verdict: Which Jounce Bumper Kit Should You Buy?
After testing eight different kits across three trucks, my top pick for the best jounce bumper kits for trucks is the RULLINE Enhanced Rear Suspension Bump Stops for half-ton Silverado and Sierra owners who tow. The progressive spring rate and 8600 lb capacity delivered the most noticeable improvement in towing stability and ride quality.
For budget buyers, the Autoacc polyurethane kits deliver OEM-quality performance at a fraction of the cost. The Best Value Autoacc Front Bump Stops for GM 1500 trucks earned 4.5 stars across 280 reviews and install in under 10 minutes. If you drive a Wrangler JK, the Autoacc JK rear bump stops are the obvious choice at 1/3 the dealer price.
For serious off-road and heavy towing, the Timbren ABSTOF justifies its premium with active compression and lifetime warranty. For HD trucks, the Autoacc HD-specific kit is properly rated for 2500HD and 3500HD suspension. For OEM purists, the GM Genuine Parts kit carries the manufacturer’s warranty and guaranteed fitment.
Whatever you pick from this roundup, you’ll feel the difference on the first bump. Jounce bumpers are one of the most affordable suspension upgrades you can make, and the ride quality improvement is immediate. If you’ve been clunking over speed bumps or sagging when you hook up the trailer, any kit on this list will solve the problem.
