Front Suspension Support

SumoSprings helper springs are great for RVs or motor homes that have slide-outs. Slide-out rooms and other heavy front loads can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front 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 rear axle, your rear 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 Rebel installed showing separation of 2-piece springs

The innovative 2-piece design of these Rebel springs allows for unlimited suspension travel. This means that there will be more movement in your suspension when you're unloaded or off-roading, which makes your ride smoother and more comfortable.


Each spring has 2 pieces. One piece attaches to the frame of your vehicle. And the other piece attaches to the axle. The pieces come together to provide support when you are carrying a heavy front load. When you're unloaded, they separate so that they don't restrict the movement of your suspension. The closed-cell urethane springs also 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 front 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 rear 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.


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.

My 2007 Allegro Bay on an F53 chassis had a real tendency to bob and weave on crooked roads and in windy weather. The Sumo Springs removed virtually all the instability. The coach handles much better and I am not as fatigued at the end of the day. 830968

Review from a similar SumoSprings Rebel in Vehicle Suspension


Drove our 38' class A gas coach for 6 months prior to installing Sump Springs. World of difference. Pulling from a parking lot to flat road used to involve 3 or 4 rock's left to right. That is gone. The porposing on the freeway is much better also. Overall feels more stable. Still shutters and has a truck like ride on rough roads and bridge abutments. 640809

Review from a similar SumoSprings Rebel in Vehicle Suspension


Installation was quick and easy. the instructional videos were the deciding factor to purchase this product. after installation everything was just as claimed. adding a 2300 load in the bed of the truck cause very little squat and actually lowered the front about an equal amount (1" in the back and 1/4" in front). since 60-70% of the trucks braking is from the front wheels this was import to me. options were airbags, adding additional leaf springs or this option. I was cautioned that when your vehicle is service with airbags installed putting the truck on a lift for oil change for example you might tear the airbag. this option on a lift the two sections just separate and go back together when lowered. I was happily surprised by the side to side stabilization removing the need for additional suspension additions. ask me again after a year 656968

The Sumo Springs made a big difference in the handling of my 38 ft class A. I had already put Sumo Springs on the rear along with an additional rear anti-sway bar, replaced the front ant-sway bar and added a steering stabilizer. Each item made improvements but the front Sumo Springs had the most impact. So much easier to drive. Installation was very easy and the online videos were helpful. I would highly recommend these. 672241

Review from a similar SumoSprings Rebel in Vehicle Suspension


Amazing! Installed Sumo springs on front of a new 2018 Thor 29.4. F53 frame. BEFORE was very unhappy with drive, could feel every imperfection on the road and steering was very unpredictable! AFTER: Dramatically eliminated the rough ride & steering issues . . . don't hesitate to buy these shocks you will be VERY HAPPY! My experience was so good I purchased the next week rear Sumo springs and the steering stabilize shock (much more improvements, but start with the front springs). 561311

Product came in within 3 days or so. Bought SUMO SPRINGS and a steering stabilizer for my 38’ Gas Motorhome and they work wonders. Highly recommed getting these items. . Feels like a different RV. 3rd time or so that I have bought from these guys, always came thru. Happy customer. And I installed front/back sumo springs and stabilizer by myself in 2hrs. 464641

Review from a similar SumoSprings Rebel in Vehicle Suspension


Excellent product. I have a 2018 Thor motor home on the Ford chassis. After purchasing it and driving it 100 miles home in sustained 40 mile mph winds, I was starting to regret buying it. Even without wind, it was a handful to drive. I purchased the sumo spring for the front and rear. The change it the handling was way better then I expected. Even in high winds. Nothing will stop all the effects of the wind on a motor home, but I can now drive it 70 mph with confidence. The biggest change was with the side to side rocking. Driving on uneven lanes and on two lane roads with out shoulders is no longer a problem. I installed them myself without removing the tires. You have to use a right angle drill. It took me 5 hours to do it, but I’m 60 years old and slow. I plan on doing other improvements like steering stabilizer and track bar. Adding the sumo spring is the best thing anyone can do to improve handling. I actually enjoy driving my motor home now. 634453

Review from a similar SumoSprings Rebel in Vehicle Suspension


When you look at the bumpstop and all the travel it can go, it makes sense to fill that space with a constant contact chusion, such as the Sumo Spring. I have a 2011 F53 chassis supporting a 32 Class A motothome. 16,000 GVW and no slide. I only installed the fronts to see how they worked. I did it myself and it took about 2 1/2 hours. If I can do it anyone that can work a wrench and understands basic mechanics can do it. I'm 60 and it's a tight space under there and takes some effort, but the jobs not hard, just doing it is hard and uncomfortable. My motorhome would ride very rough on the same roads my car ran smooth. The Sumo Springs were an improvement. They did not solve the rough ride on real poor highway, but on normal rough roads, they were an improvement that will benefit the ride on more roads than not. I now plan to do the rears when I get time. 500303

The installation instructions for both the anti sway bar upgrade and the Sumo helper springs lacked torque values for their fasteners. Both suspension components fit correctly and have improved how our class A motorhome handles. Great service from etrailer. 556109

After a year, I’m still convinced the Sumo Springs was money well spent.

Review from a similar SumoSprings Rebel in Vehicle Suspension


The SumoSprings item #SSF-170-40-2, for my 2017 Georgetown GT3, with the F53 Ford chassis was very easy to order from etrailer.com and was shipped in a very timely manner. They came with easy to follow installation instruction. Be advised that you will need a 1/2" socket with a 3" extension to insert into the factory bump stop to hold bolt while removing the nut on the drivers side. This is not mentioned in the instructions. You will also need the same socket and extension to remove the bolt on the passenger side. One other note, the nut on the drivers side is a 15mm. Other than the afore mentioned 1/2" socket and the 15mm the only other tool you'll need is a 9/16". About a hour and a half to two hour job. I took the motorhome for a test drive and there is a very noticeably improvement in the ride. Very satisfied with my purchase. Thanks, sumosprings for a great product and etrailer for a great price. 566821

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 688201

Review from a similar SumoSprings Rebel in Vehicle Suspension


Preston did a great job helping me spec in the correct springs for my 2016 Thor Hurricane 27K on a F53 chassis. Placed order with him over phone and received springs two day's later. I just installed them and took Motor home on a test drive around town on bumpy streets and what a difference it made. Drives more like a truck now and less like a boat. I also installed a steering stabilizer spring and did the cheap handling fix to the sway bars. Well worth the time and effort. I did notice that the etralier installation video shows the bottom brackets of the spring installed with the "U" down which is opposite the mfg's printed instructions. I did mine according to the printed instructions cause it seemed to make more sense. Probably no big deal either way. Thanks etrailer. I'll be contacting you guys when ready to do the back end of my motor home. 649992

My THOR motor coach has the Ford F-53 chassis. I rides like a truck. That should not be surprising as "it is a truck." I purchased and installed these Sumo Springs and even though it will never be "air bag" suspension, the Sumo Spring made a wonderful difference in improving the ride. I would recommend this add on to everyone and as I meet similar motor coaches on the road, I show them the Sumo Springs and I do recommend them. 868931
