Rear Suspension Support

SumoSprings helper springs are great for pickup trucks. Towing or hauling a heavy load 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 truck'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 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, typically above your existing factory leaf spring. The pieces come together to provide support when you are towing or hauling a heavy 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 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.

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.

2016 Chevrolet Silverado 2500

I installed these this afternoon. The install was relatively easy but had to deal with e-brake line guides that had to be modified. The springs have very little gap between top and bottom (close to zero). Unlike the reviews I read before purchasing, the unloaded ride quality was extremely uncomfortable. I'll check with etrailer tomorrow for possible remedies (1" lift block on rear end to create gap?) If the unloaded ride can't be fixed I will try for a return and buy air springs. Stay tuned, the rating can only go up.

The instructions state that e-brake lines and other possible cables may have to be rerouted and pinned up by zipties. These springs do not have a gap when on the ground. Item # SSR-203-40-2
SumoSprings Rebel Custom Helper Springs - 2 Piece - Rear Axle
would be good for recreational towing jobs. The springs you purchased are higher rated and would be used for constant work applications. The higher rated springs are stiffer and will have a rougher ride than the recreational lower rated springs.
-- Etrailer Expert Sierra K - 05/17/2022


They fit fine and installed as described in the printed instructions. Reasonably easy overall, even for a novice like me. My only comment is that the video that was included showed a different set up than what was delivered. That made me unsure if I had the proper system for my truck, which indeed I did, but the difference between what was shown in the video that was "for my truck" and what was in the box had me wondering. Never-the-less, all was correct and went well.

Product is excellent. The springs really reduced the squat I used to have in my truck when I hooked up my fifth wheel camper. Actual reduction in squat was around a 2 inch change. This also keeps the nose of the truck from rising in response to the rear sag I used to have, which makes the overall handling of the total rig a bit better as well. Also, the ride, while connected, is noticeably smoother and feels more stable while driving in stout crosswinds, which we frequently enjoy, here in Oklahoma.

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


I don`t write review`s but I`ll tell you these thing`s are very good, never need air so there`s no leak`s so if the Border Patrol uses them it`s good enough for me ...


The sumo shocks arrived faster than was told. Fantastic products and great customer service! Nicole who took my order was great! Thanks again Nicole you are exceptional in the customer service dept. at Etrailer. Second time ordering from them out standing company and great employees, You Rock!!!!!

Worth every penny. Improved ride and ha ndling.


Springs performed exactly as described. The professional staff described how to measure the truck with and without 5th Wheel load and sent the springs I needed. Since installation the level has maintained and steering and ride improved. Etrailer staff got me exactly what I needed.


yes i liked the SumoSprings bether than the air springs i had on my last truck


Received SumoSprings and installed them on Chevy HD2500 Duramax that same afternoon. Took about 1-1/2 hrs. and instruction was straight-forward. Watch etrailer [install video] will save you some time. Will test out ride this weekend while pulling 5th wheel RV.


Great service. Easy install.


Excellent quality and just what we wanted. Thanks again etrailer!!

Review from a similar SumoSprings Rebel in Vehicle Suspension

The front Sumo Springs made a major difference in the stability of my Winnebago motorhome. It handles the bumps much better without major jarring of the passengers and dampens the side to side motion in turns and under crosswinds.

After a year of use, this product is the best investment I have made to my Winnebago motorhome. I highly recommend adding Sumo Springs to any gas motor coach to improve stability, ride, and safety!

Review from a similar SumoSprings Rebel in Vehicle Suspension

Sumo springs along with a steering stabizer, new shocks, and oversized sway bars seriously tightens the ride on older model RV with an f53 ford chasis. Long hauls become a lot less strenuous. I also put a memory foam and high density foam seat cushion on the driver's seat. We can travel all over with a lot less fatigue from fighting the wheel and pucker factor from blowing around the road. I took about 3 hours to unstall all 4 sumo springs.


Review from a similar SumoSprings Rebel in Vehicle Suspension

Just Installed my Sumo Rear Springs. They went in real easy on my Dodge Ram 3500. The thing that took the most time on the install was jacking up the frame 3-4" to make enough space between the axle base and top of frame to slip in the entire lower and top sections of the Sumo Springs. Once I did that, I narrowed that space by letting the frame down a little but not all the way. Just enough to catch the receiving spring and leaving a half inch gap between the two sections. This allowed me to easily rachet the bottom u-clap without a problem and keep good alighment. I know I'm going to love this product once I hitch up. No more 2' drop in the rear end once hooking up to my 15k 5th wheel. These springs are stout but no so stout I'll beat the hell out of my body when hunting the rutted roads of the great North West. Thank you Jessie for your expertise and steering me toward the perfect application to meet my pulling and off-road needs.


Review from a similar SumoSprings Rebel in Vehicle Suspension

We have a 2009 build F53 chassis on our 2010 Windsport 32A. I ordered these Sumo springs for the front axle. Hated how bad our coach dashboard would shake and rattle when going over bridge transitions, potholes, and concrete roadway section breaks. Took about an hour and were easy to install alone. Couldn't believe how much these helped the front axle. Worked so well I recently bought a set for the rear axle also. Those are a bit harder to install due to having to drill holes in frame rails to mount the upper bracket and glad I had friend to assist me. Would have only taken a little longer without the help but still easy to do by basic mechanic skills. With having both now we can certainly tell the difference and wished I had bought them sooner.

Our Sumo springs have been the best addition we have made to our coach. Now retired, we have been getting out and driving farther and the Sumo Springs have made the ride so much better. Highly recommend them on this F-53 chassis.

Review from a similar SumoSprings Rebel in Vehicle Suspension

I bought the Summo Springs for the front and rear of my Thor ACE 30.3 because I could not find the bigger anti-sway bars for my F53 chassis. I was very disappointed with the way my MH handled. The Summo Springs did a great job of stabilizing my MH. 100% improvement. I would Highly recomend them and etrailer is very good to work with

After a year and 15000 miles I am still very happy with my choice of Summo Springs

Review from a similar SumoSprings Rebel in Vehicle Suspension

We have a Ram 3500, carrying a 5000 lb (plus), extremely tall truck camper. The floor sits ABOVE the side rails of the truck bed. I came to the RV dealer, and of course, they would not let me have it till they inspected the truck. It HAD to be a dually to handle street corners. The inspector saw the air bags that the truck dealer had installed and commented that "You will be a lot better off when you buy some Sumo Springs. After one trip cross country, I ordered Sumo Springs, and have not regretted it since. Stabilizes this super high load on corners, cross winds, and general driving. At night, truckers no longer flash their headlights at us. This is the way to go.


Review from a similar SumoSprings Rebel in Vehicle Suspension

took about 2 1/2 hours to put them on. Love them!! Trailer sits level and truck still has it's proper angle to the road!


Review from a similar SumoSprings Rebel in Vehicle Suspension

We recently installed the Roadmaster Sway Bars along with Sumo springs from trailer on our 2017 Winnebago Vista 31T which utilizes the Ford F53 chassis. What a game changer in the overall ride and handling. Customer service was excellent and I highly recommend the company for their high quality product.


Review from a similar SumoSprings Rebel in Vehicle Suspension

As far as bang for the buck, these are probably the best improvement to your suspension that you can make. Of course there are additional upgrades (improved sway bars, front and rear, and a steering damper), but they are at least twice as much as the cost of a front and rear set of these. I was able to install the front ones myself, but the rear requires drilling the frame and/or removing the rear wheels, so, I had the rears installed by a shop.


Review from a similar SumoSprings Rebel in Vehicle Suspension

Purchased the SumoSprings Rebel Helper Springs for my 2021 Tiffin Open Road Allegro. Installation was not difficult. The ride quality has improved. Previous jarring rough pavement bounces are substantially reduced.


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.
