Rear Suspension Support

SumoSprings helper springs are great for RVs or motor homes. Heavy rear loads can cause sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the motor home's weight. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.

SumoSprings diagram of installation above existing vehicle spring

Each spring in this kit is bolted to two mounting brackets. One bracket is attached to the frame of your vehicle, and the other bracket is attached to the axle, typically above your existing factory leaf spring. Because each helper spring is in full contact at the top and bottom of the suspension's travel, the expanding and contracting action of the SumoSprings enhances your ride under all conditions, not just when it's loaded. And the closed-cell urethane springs act like a shock absorber to dampen road vibration.

SumoSprings compressing under load

SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.

The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.

SumoSprings expanding to allow play in the suspension

These springs extend in height by as much as 50 percent to allow more movement in your suspension when you're traveling unloaded, making your ride smoother and more comfortable.

Durable, Custom-Fit Springs

These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).

SumoSprings expand and compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.

This kit comes with custom-fit brackets that are designed to easily bolt onto your vehicle.

Best purchase you can make for the f53 chassis. I can't believe how big a difference these things make. Very nice ride. Can actually drive for hours now and not feel fatigued. I recommend to buy these first thing when you get a new motorhome. 677974

Already had front sumos and my thought on them is lukewarm. I installed the rears and test drove it yesterday. Wow, what a difference when turning corners and entering/exiting driveways with a lip on them. No more rolling from side to side. My wife rode along on the test drive and also felt the difference almost immediately. It just feels stable. I highly recommend this product. Did the install myself in about 2 hours without pulling the wheels, just make sure you have a good right angle drill for the bottom rear holes. 547447

Chevrolet Silverado 1500

Wow what a difference. We have had the Sumo springs in for about a year now. We have made several trips including a couple over 1500 miles and the ride and handling are so much better. The key points for us have been the smoother ride and faster recovery from dips and bumps (one porpoise and settle!). Also the improved handling at corners and turns because the rig doesn't lean as much. The big review is from my wife who was not really enjoying our class a before because the ride was making her a little sick. She is very happy now and will be the first to tell folks about the springs. As for install, two old guys that aren't really big DIY car guys took 2 days and a few bruises but we installed at all 4 corners. And without having to call anyone for help! The video from etrailer was a key factor there. The tip on removing the wheels for the rear install was probably the biggest piece I got from it and honestly I'm not sure how you can drill those holes without doing it. I highly recommend the Sumos and etrailer was fantastic in getting products shipped and providing good support info to make the install easier. 714913

These made a huge difference in the drivability and handling of my 2018 Ford F53-based bounder 35K. Highly recommended. And the team at etrailer.com is super responsive and helpful. I strongly recommend this upgrade, combined with additional/reinforce sway bar. You driving will be more pleasant, less stressful and safer. - Vittorio 690868

The Sumo Springs have made the ride on my 2016 Thor Challenger much better. The coach doesn’t lean as much and feels more stable. 665928

- SSR-187-54-1

I had the both the front and rear sumo Springs installed on my 2016 Newmar Canyon Star, by the crew at Etrailer. The improvement in the handling was noticeable the minute I hit the road. The most noticeable effect was the reduction in the top heavy sway when cornering. It also seems to have reduced the effect of passing semi's . I would definitely recommend this product to anyone who has a Ford F53 chassis on their motorhome. 661101

2011 Ford F-53

I purchased a 2011 Georgetown motorhome in 2011 which uses a Ford F-53 chassis. I wish I knew better at that time. I realized that driving it was stressful and dangerous due to the body roll and micro lunges when driving rough road or windy day or curvy roads. We limited our trips to around 200 miles due to this. I had to do something. First, the rear sway bar I bolted the connecting links to the inside bolt holes and replaced the shocks. It drove much better but still some body roll and micro lunges. So I decided to take the next step. I purchased Sumosprings for the rear and front axles. They were exceedingly easy to install, worst part was drilling the frame for the rear axle. I have now been on a trip on mountain roads for two weeks. The micro lunges seem to be gone, almost like driving a car. The body roll isn't an issue anymore, I can drive the mountain curves without feeling like being thrown over a cliff. There may be other ways to fix this Ford F-53 problem, but the Sumosprings do the job. 542019

I read many reviews on this product,but let me tell you there is a amazing difference in the handling of the coach. you can feel it as soon as you go around a corner. The coach is now more stable with side to side movement without sacrificing ride quality. I am glad I went this route instead of adding sway bars. 520286
