Features to know about

Stay Level and Confident Up Front: 1,500-lb Front Suspension Support

A heavy front load like a snowplow or winch can make your front end drop and throw off braking and steering. These SumoSprings Solo helper springs add up to 1,500 lbs of support at 50-percent compression to keep your ride level and balanced. They help your factory suspension carry the weight so your headlights stay aimed right and your steering feels steady.

Smooth Out Every Bump: Progressive Load Control

Roads and loads change, but these springs adapt on the fly. Their progressive load control means they compress softly with lighter loads for a smoother ride, then stiffen as weight increases—up to 80 percent compression—to handle the extra strain. The result is less bounce, fewer jolts, and a comfortable ride whether loaded or empty.

Stay Steady in Crosswinds and Turns: Independent Spring Action

When a curve or uneven surface tries to push you around, each spring works on its own to keep both sides stable. That independent action helps cut down on body roll and sway so your vehicle stays planted through corners or when you hit a bump on one side.

Built Tough for Real Conditions: Microcellular Urethane Construction

Made from durable microcellular urethane, these springs resist damage from oils, road salts, and UV rays while performing in temperatures from -25 F to 200 F. They compress straight up and down with minimal side expansion so they fit cleanly even in tight spaces. And because they’re maintenance-free, there’s no tubing to run or air pressure to check—just install them and get back to driving.

Quick Setup That Fits Right: No-Drill Installation

These custom-fit helper springs mount directly using existing points with simple hand tools—no drilling required. In just a short time you’ll have solid front-end support that levels out your ride and keeps it steady under load.

What most new RV owners don't know is that the chassis that their new mobile home sits on barely has the equipment to support that new home. Adding SumpSprings is going to improve your ride and help support the structure of your home. FYI, use a jack on the leaf springs to help align the holes on the bracket to the ones on the frame.

30 Minutes for all 4?! That's got to be some kind of record, Dennis! Glad the process was nice and easy and I hope they serve you well. Let us know if you do end up needing to go to the heavier duty yellow option as well, we always like to get real life experiences from people. : ) Any more trips planned for the year?

2018 ford F-250 Super Duty
eTrailer made the choice easy by offering advise on options and applications. Installation was also quite simple, though the directions were a little too simple. However, I was able to determine once installed prior to final torque, that the top plate could be rotated to align the helper springs with the corresponding flat plate on top of the differential/axel perch. Honestly, with daily driving if there is a difference I cannot tell, which is a GOOD thing. My F250 Powerstroke diesel, like most others, unladen has a firm ride. I did not want it to be more so. My 2018 does not fit in my garage not even close. So outside 24/7 since purchase, the OEM bumpstops at all 4 corners needed to be replaced and I wanted to upgrade them. These are quality no-maintenance bumpstops, and did not require any additional spacers to fit properly with my 2-2.5 inch leveling spacers. Paired with the Timbren SES for the rear, my Super Duty is set for all of my needs, including light to medium hauling / towing, for the foreseeable future. A huge shout-out to all of the people I spoke with for both purchases - thank you for all of your advise and assistance!!! eTrailer will most certainly be a first-stop should I need help with anything else I may need from all of their other and quite expansive upgrades for my rig.

I have a Workhorse W22 chassis. I installed steering dampeners and HD sway bar to reduce the "loose" steering. After installing the SumoSprings Front Spring helpers on the front end, 90% of the looseness on the front end disappeared. It is now a pleasure to drive. Very little sway from passing trucks and cross winds. I will be installing a set on the rear this year.

That is awesome to hear! It must be such a relief to not have to put so much energy into controlling the wheel while driving now.

by:
Product is great, exceeded my expectations. Install is simple and straightforward. It’s a night and day difference in both the body roll and the handling small bumps all the way up to off-road conditions.

Appreciate you leaving a review Austin, It's always nice when a product exceeds expectations and these springs have been highly rated. Are you typically off road or do you plan on towing?

2018 Thor Freedom Elite Motorhome
I recently purchased/installed SumoSprings for the front axle on my 2018 Thor Freedom Elite 28FE. Having previously purchased/installed SumoSprings for the rear axle I have to say that the overall improvement in ride/handling has exceeded my expectations. As always, etrailer provided valuable insights and prompt inquiries to my questions. The level of in-depth product knowledge amongst the etrailer staff is second to none. Thanks etrailer!

Original bump stops were dry rotted and almost not existent. Very easy install. Took about 30 minutes. The Sumo springs are engaged all the time. This may be due to the truck being a 4x2? You can feel the front end is stiffer over bumps and dips of the road, which I feel is ok and not extreme. Towing the 5th wheel I feel the truck handles better than before.
by:
Ordering and delivery was quick and easy. The SumoSprings really improved the ride of our C Class RV. The only problem was one of the springs had cross threaded threads so I had to tap the treads to make it work. They were delivered in a plain brown box with no manufacture information or instructions. It makes believe the were a returned item, the previous purchaser couldn't get them to work either. I just had the tools and skill to correct the problem.
by:
These Sumo springs (as well as the ones I purchased for the rear of my RV) installed easily, fit perfectly and do a great job reducing vibration and improving ride quality. Very pleased.

Installed front Sumosprings yesterday but have not driven vehicle yet. The front have full contact with the A-frames.
Should help with van side-to-side sway
.
Shopping around for a set to install on the rear as well.

Installed Sumo Springs on my 2019 Chevy 4500 motorhome, I was looking for ride improvement without breaking the bank. These days so many products are marketed well but never match the performance that was promised. That is not the case with Sumo Springs!!! I am very pleased with the ride improvement, sway is gone when transitioning from different levels of pavement and the shock of bumps is 50% better!! Installed myself on front and back in about 1 hour, front ended up about 3/8” higher after a couple days, got front end alignment done but didn’t need any adjustment. Finished a 400 mile road day today and my wife and I are very pleased. Excellent product!!

That's awesome to hear, Edwin! Where did you head off to?

by:
2022 Winnebago Navion Motorhome
I’ve made several purchases from eTrailer and have been satisfied every time! Recently bought front and rear Sumo helper springs. Installation was a breeze. They have helped reduce the side to side sway caused by wind, freeway traffic and rough roads. So far im very happy with them.

Sumo springs greatly reduced body sway on my 2021 Mercedes Sprinter.
by:
these look like the perfect thing for my tired old helper springs, I put SumoSprings on my rear axel of my Jeep a year ago and the have made that ride much better hoping for the same with these.
by:
2009 Winnebago Adventurer Motorhome
Have not had a chance to install yet but seem to be a lot better than what was on my RV. One thing I have noticed is the old part screws into a nut welded on the frame and the new SumoSpings bolt is to small to use the welded nut. So installation would be a lot easier if you could just screw it in.
by:
Sumo Springs really helped with the bumps in the front of the 2019 Ford E350 Winnebago! Very happy with them. Super easy install even though a bit awkward to reach the spot.
by:
Very easy installation. Would be nice if they were about 2” longer to get contact sooner but they were a good replacement for the hollow stock bump stops.
by:
Springs arrived on time without any damage. Installation was completed in about a half hour with a 10mm socket, 3” extension and ratchet to remove the stock bump block on our Ford E450. Then just thread the Sumo Spring in place of the removed block. This was the easiest upgrade I’ve done so far.
by:
Put these on a Sprinter and what a positive difference they made. One can still feel the poor shape of our roads but no more jarring as was the case before. Definitely worth it.
by:
toyota Tacoma
Springs are good, working well. My Tacoma is stock (no lift). With the front end jacked up and wheel/tires totally suspended I was not able to get the springs mounted. I had to cut off about 1/4 inch of threads to get them into position to screw then in. Once that was done everything was ok.
by:
Already had Sumos on the rear, finally got around to adding them to the front, removed the bump stocks, they looked exactly like the Sumos but were a little softer, wasn’t sure it would make a difference, boy was I wrong. Test drove her, huge improvement on cornering, much less lean, better handling, etc. very pleased with this improvement. My RV is a 2007 35’ Winnebago with a W22 Workhorse Chassis.

That's really awesome to hear! I'm glad you like the Sumos. They really are a great option. Are you full timing in the Winnebago or just using it for longer trips?

by:
gmc Sierra
Installation in a 2022 Sierra 2500HD was easy, used large Channel locks to remove factory, new ones popped in by blocking them with wood wedge while vehicle was jacked up and releasing jack quickly so all weight would come down at once.
Only have aprox 100 miles on new Bump Stops but ride feels smoother as they are engaged at rest, unlike factory that engage on bumps. Need more miles to fully review.

These Sumo springs were a great upgrade. So easy to install, less than 20 minutes.

It was a great investment. It truly helped with the front end bouncing. I look forward to adding a set to the rear.

@Deborah Glad to hear it! Whenever you decide to throw some SumoSprings on the back of your 2004 Workhorse W-Series chassis you'll be looking for the Kit # SSR-280-54-1.
by:
Ordering was easy and shipping was quick. Installation was Super easy, took longer to lift Motorhome and set Jack stands then to install The SumoSprings.
Ride was much smoother and body roll was much improved.
by:
Installation was a straightforward and easy. The SumoSprings made a huge difference in the handling of the RV. The large sway left to right from wind or passing semi trucks has been effectively eliminated make the RV much more comfortable to drive.

  • Recommended SumoSprings For the Front Axle on a 1999 Ford F-250
    I had the SumoSprings Solo Custom Helper Spring # SSF-103-40 measured and it will be 5-1/2 inches tall from the bottom of the spring to the top of the bracket. The blue # SSF-103-40 will also measure the same as the black # SSF-103-47. Deciding between the two will depend on how much support you need. Between the two, however, I would go with the blue # SSF-103-40. This will affect the ride less than the more heavy duty black version. If you are carrying a lot of weight and need the extra...
