SuperSprings Intl Vehicle Suspension - SSF-402-54
Highlights
- Custom Fit for Your Vehicle: Mounts to existing attachment points
- 1,400-lb Front Support: Keeps your ride level and steady when carrying heavy front-end gear.
- Smoother Off-Road Control: Absorbs big bumps and shocks so steering stays predictable on rough trails.
- Zero Maintenance Required: No air lines or pressure checks—just install and drive worry-free.
- Progressive Load Response: Stays soft for lighter loads and firms up to 80% for heavier weight.
- Faster Engagement Design: Taller springs engage sooner to reduce front-end sag and improve handling.
Features to know about
Stay Stable Over Rough Terrain: 1,400-lb Front Suspension Support
When front-end weight or uneven trails make steering feel sketchy, these helper springs add up to 1,400 lbs of support at 50-percent compression. They absorb big bumps and shocks that happen off-road, keeping your ride level and steering predictable even when heavy gear is mounted up front. The taller design engages faster than standard helper springs so control doesn’t fade when the terrain gets rough.
Smooth Out the Hits: Progressive Load Control
Every bump doesn’t need to feel like a jolt. The progressive design means the springs compress softly at first for light loads, then firm up as weight increases—up to 80 percent compression for heavier setups. That balance keeps the ride comfortable when cruising light while adding solid support when things get heavy or uneven.
No Fuss, No Maintenance: Solid Urethane Construction
Forget about airlines or pressure checks. These are made from high-density microcellular urethane that works from -25 F to 200 F and resists oils, road salts, and UV damage. They compress vertically with minimal lateral expansion so they won’t rub or bind in tight clearances, and you don’t have to worry about leaks or upkeep like air systems need.
Quick Bolt-On Fit: No Drilling Required
Getting extra suspension support doesn’t have to be a project. The kit bolts above the existing front axle springs using the included hardware—no drilling or routing lines needed. Once installed, the pair of helper springs stands ready to take on heavy loads, off-road travel, and whatever uneven ground you find next.

Good product, length was to long and had to shorten it 2 "rings" to allow up travel and not contact stop on every bump. I installed a 2.5" clayton coil spring lift and the between the new lower stops summo springs was only 2" of travel. Might be fine on factory vehicle without lift. These are a huge improvement over factory bump stops that had very little cushioning effect.

I put these on my 2017 2 door jeep wranger. I have factory springs no lift. I put on aftermarket front bumper with wench, rear bumper, roof rack. With all the other gear in the jeep, frig, and all camping gear, and plans on putting on a rooftop tent. The ride was a harsh because off all the extra weight, so i thought i would give it a try. I first got air bags for the rear and they worked great, improving the ride, but now the front was still harsh. So i thought i would try the sumosprings. All i can say about the sumosprings is that there awesome. I can now go over bumps on dirt roads, paved roads, train tracks, and it dosnt beat the crap out of me. Jeep feels like its happy.

SumoSprings for the front end, the provided bolts are the exact size of the holes in the frame. Had to keep forcing them till it started to thread then use plyers to hold it in place. Very tough to get it but it went it. Have a 2006 Pleasure Way Dodge Sprinter 2500 RV Class B.

I used them as high speed bump stops. They work great and much cheaper than air bumps.

I am sure these would have helped the Gladiators without the factory Fox hydraulic bump stops but in my case I returned my purchase I opted not to replace my Fox hydraulic bump stops in the Mojave.

See what our Experts say about this SuperSprings Intl Vehicle Suspension
- Looking For Sumo Springs For My Jeep With A LiftHey Steve, The # SSF-402-54 kit is not going to raise the rear of the Jeep necessarily. It will help when a load is presented to keep the ride level. With your lift that you have you will need spacers to make up for that gap. For your Jeep I recommend the spacers for 4" # SS32EV. This will accommodate for that needed space and get you set. Are you towing or anything with that Jeep?
view full answer... - What SumoSprings For Stock Height 2023 Jeep Wrangler 392 JLU?Hello Lu, thanks for reaching out. For a stock height 2023 Jeep Wrangler JLU you will want the SumoSprings without the 1" spacers. What I recommend is the following: - SumoSprings Solo Custom Helper Springs for Jeep - Front Axle - Off-Road # SSF-402-54
view full answer... - Recommended SumoSprings For A 2006 Roadtrek Adventurous RS Class B MotorhomeHey Brian, For a 2006 Roadtrek Adventurous RS on a Dodge Sprinter 2500 chassis you'll need the SumoSprings Solo Custom Helper Springs - Front # SSF-402-54 and SumoSprings Solo Custom Helper Springs - Rear # SSR-329-47. These are the only SumoSprings confirmed to fit your chassis. The # SSF-402-54 has a 1,400lb capacity and the # SSR-329-47 has a 900lb capacity so you're on the lower end of the capacity spectrum and shouldn't have a ride quality issue with these additions.
view full answer... - What Suspension Upgrades Should I do for My 2023 Jeep Gladiator Mojave for Overlanding?Hello Chuck, Happy to get the right suspension upgrades for your 2023 Jeep Gladiator Mojave. Since you mentioned load leveling I would go with the air bags. The Air Lift LoadLifter Air Helper Spring Kit w/ Air Spring Cradles - Rear Axle # AL88FF. The bags are great for helping with sway and body roll. These Air Bags fit every concern that you have. If you needed a great air compressor to pair them with, check out the Air Lift WirelessAIR Compressor System for Air Helper Springs - Remote...
view full answer... - Will SumoSprings Coil Helpers Fit Front And Rear Axle Of 2023 Jeep Wrangler JKUHello Quang, thanks for reaching out. Yes, you can use the Coil SumoSprings Custom Helper Springs for Coil Spring Suspension # CSS-1094 on both the front and rear of your 2023 Jeep Wrangler. Also, you can indeed use them with SumoSprings helper springs in you wish. The kits for your Jeep are the following: - SumoSprings Solo Custom Helper Springs for Jeep - Rear Axle # SSR-405-47 - SumoSprings Solo Custom Helper Springs for Jeep - Front Axle - Off-Road # SSF-402-54
view full answer... - Front Suspension Enhancement for a 2025 Jeep WranglerHey, Steven! The Air Lift 1000 Air Helper Springs for Coil Springs part # AL60829 will fit your 2025 Jeep Wrangler, but only for the rear. The best option for the front axle of your Jeep would be SumoSprings Solo part # SSF-402-54 or the Coil SumoSprings part # CSS-1168F. Both of these would have similar affects as the Air Lift 1000 Air Helper Springs and would give you that support you are looking for. Are you planning to carry something on the front of your Jeep?

I really like what you're doing here it will really help out in the long run and prevent the typical permanent sag we see a lot in vehicles that are used for plowing often. In your case I recommend going with the SumoSprings Solo Custom Helper Springs for Jeep - Front Axle - Off-Road part # SSF-402-54 like you said these re going to engage more quickly than the SumoSprings Solo Custom Helper Springs for Jeep - Front Axle part # SSF-401-54 .

The Rear SumoSprings # SSR-338-54 are 6" tall, 4" long and 3" wide. The Front SumoSprings # SSF-402-54 are 3-1/2" tall and 2-1/2" in diameter.

- Suspension Enhancement for Front and Rear Suspension of 2016 Jeep Wrangler We have front suspension enhancement that does fit your 2016 Jeep Wrangler and is intended for off-road applications like I can see in your picture, but we don't have any air bag style kits. Instead we have jounce bumper style kits like the SuperSprings kit part # SSF-402-54 which will fit and work well. The tall microcellular urethane springs absorb big bumps and shocks and engage sooner than standard springs. For a matching set for the rear axle we have the part # SSR-405-47 as well.

- Recommended Suspension Enhancement For Sway & Leveling on 2006 Dodge Sprinter 2500Ok, so there are a couple things you can add to get the best overall performance to help your 2006 Dodge Sprinter 2500 to help with sway/leveling/bottoming out. First, I'll go ahead and list the parts: - Front: SumoSprings Solo Custom Helper Springs # SSF-402-54 - Rear: SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SS62KV The combination of both parts are going to give you a much better overall ride. As for the rating of the springs, Your question is perfectly understandable...
view full answer... - Suspension Enhancement for 2025 Jeep Gladiator Rubicon With Factory LiftHey Kathy! I think that would be a great combination. Are you bottoming out on the front and the rear with the tent installed? If it is more the rear I would go ahead and install the Timbren Active Off-Road Bumpstops # TABSJFTJ back there and see how it does. You may find that the front isn't really necessary and you'll be saving yourself some money. If you still think you need it, you can always add the # SSF-402-54 later. Where do you typically take your Gladiator and rooftop tent?
