Rear Suspension Support
SumoSprings helper springs are great for vans. 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 van'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.
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 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.

The Sumo mount had to be slightly modified on the drivers side (removed a 1/2" by 1/2" chunk of the plate) with a grinder to get it to fit on my 2022 f350 4x4. I contacted the manufacturer prior to making the modification. They did not have an issue. The Sumo reduced truck squat (approx 3/4") allowing the truck to ride level with a trailer (8k hitch mount and 17k gooseneck). When you hit a pothole, the impact felt in the truck was jarring and caused the truck to become unstable. The Sumo eliminated this problem. I chose the blue over the yellow after watching a video on etrailer about ride comfort. I added front Sumos after I installed the rear Sumos. The rear provided the a more noticeable improvement. I chose Sumos over air bags because they eliminated air leak maintenance and air pressure adjustments depending on the load.

These things are amazing! I had doubts, but I figured for the price why not give it a try. The sag is gone when pulling my 5er. My 350 has a 3” lift and sits perfectly level unloaded so any sag shows instantly. These “springs” eliminated the sag and made the ride10x better. Only dropping one star because the kit only came with 4 flange nuts, supposed to have 8 in the kit. Luckily I had 4 with the correct thread pitch laying around.

Front and rear Sumo Springs installed. Have not had a chance to hit the highway as yet. Locally a very good ride. Thanks to Joanne K. for all of her help.
by: Dwight 05/07/2023
they were a great investment for our motorhome. Swaying now is very little and it has to be very windy for me to notice. I will never own another motorhome without sumo springs. I have a forest river fr3 30ds 2021. Easy to install yourself.
by: KLee10/25/2021
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.
by: Ed04/10/2020
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.

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.
by: Thomas04/28/2023
These helper springs made an amazing difference in the stability and ride comfort in our coach. Improved cornering and bounce control were immediately apparent. Plus, crosswind driving is much improved. The split design makes leveling easy as I typically raise the front of the coach rather than the rear. Installation is a lot of work, but can be done yourself with the right equipment. Very pleased.
by: William05/25/2023
The work great! Was going to go with the Air-Ride air bags in the front but folks had noted that the bags are strained when the leveling pulls the front wheels up to the point of coming off the ground. Glad we went with these. The person I put this on for is Handicap (or Handicapable as she says!) and these do not require air or making sure the pressure(s) are correct and holding.
It was a pain in the butttt get the original jounce bumper off the drivers side, but we muscled through it!! Thanks, Amy, for your help in ordering!! v

I put a small leveling kit in my 2500hd Silverado. I noticed afterwards towing my excavator or dump trailer I was getting some rear sag when I had my trailers loaded heavy. I considered doing air bags for the rear. Instead I installed the sumo springs. I installed them in about an hour. Very happy with them. No noticeable difference in ride quality while empty. And they keep my truck level when I’m hauling my trailers. 5 stars!
by: Peck03/04/2024
I installed the Sumo Springs prior to a 7500 mile trip on my 22GMC 2500. We was pulling our 34 foot Travel trailer and I believe the springs made all the difference in ride stability as well as control while pulling.
by: Monte11/16/2023
Ordered the sumo springs on a Thursday and received them on a Thursday used the on line video they have had had them installed in no time this isn’t the only product I have gotten from them and will continue to use them great service
by: Chris 04/29/2024
Game changer! The factory should be required to install these on every motorhome. From white knuckle carsick swaying and wandering to a one finger smooth ride. Highly recommend!
by: WD Qualls04/06/2024
Bought these for my 3/4 ton. Oh my god, roughest ride . Removed these springs and replaced with air bags.
by: Timothy01/18/2024
I think they helped with the side to side roll I put on front and back sumo’s the roadmaster sway bar and front safety steer. Drove from Michigan to Utah . I think the ford f-53 is not a great place to start
by: Tracy 02/18/2024
A friend and I installed these, if was not difficult to figure out and was a big savings. My wife noticed the difference without knowing it. On a trip to a frequent location she would complain the entire trip after installation on the same trip she did not complain at all. Success!
by: Sergio12/11/2023
The installation went very well. The ride seemed smooth.
by: Dan Coleman, THOR 2018 Windsport, F-5308/26/2020
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.

If you are looking at these, betting you have a class A that you are attempting to get the smoothest ride out of. We installed these on a V8 F53 24k chassis - Georgetown G7 for the same reasons. Most forums and reviews speak of multiple components being installed all at once, with varying results on ride quality. Being an aircraft mechanic of 20yrs, I elected to install one component at a time before throwing the store at it. Started with the Koni Evo shocks. Really helped smooth the ride and lessen the low speed rolls. So much, we almost stopped there. After reading many rv’ers speak to front and rear Sumos being too stiff of a ride, I elected to only install fronts. The fronts are two piece bags unlike the rear, which means the only dampen on compression, not extension/compression at same time. My theory was correct! For us, this is the perfect combination at minimal cost! I highly suggest you start with this setup prior to buying the store!

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.

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.

The Sumo Springs have a 1,500 pound capacity. The helper springs keep your vehicle level when you're towing or hauling a heavy load, help to absorb bumps and shocks, and minimize sway.

Whereas, the SumoSprings Rebel # SSR-128-40-2 have a maximum capacity of 3,000lbs at 50 percent compression.

These springs are progressive so when you are driving with no weight or little weight it will not act harshly like some of the other heavier rated springs. As weight is added to the suspension the springs will compress adding additional support to your suspension helping to keep your F-250 level and provide you with a stable ride.

The 4x4 and 4x2 models of your truck have slightly different suspension setups which is why there is a different fit created for both versions.
view full answer... - Weight Capacity of SumoSprings Kit # SSR-128-40-2The weight capacity of the SumoSprings part # SSR-128-40-2 that you referenced is 3,000 lbs currently as it was recently uprated. Thank you for bringing that to our attention we'll get that updated ASAP. What's worth noting is that this kit will provide your factory suspension with 3,000 lbs more support to help it carry it's current weight capacity as safely as possible but does not give you additional capacity beyond what the truck is rated for.

The Rebel's 2 piece design allows for better compression and movement with the axle, giving you a better and more comfortable ride. The higher capacity, though pretty small, does also lend itself towards more heavy duty trucks, like your 2022 Ford F-350. This means they will suit your needs better and will be the better option.

The kit I recommend for your 2022 Ford F-350 4x4 though is the Rebel kit from SumoSprings: - SumoSprings Rebel Custom Helper Springs # SSR-128-40-2 The reason I like this over the Timbrens is because the Timbren springs tend to be less forgiving. While that initially sounds like a good thing for heavy duty towing, it also means you're going to feel it when you aren't towing. SumoSprings has done an excellent job at combining...
