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.

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:

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.

Just as advertised. Easy install and doesn’t affect the ride. Will purchase again

I had these on my last truck and they worked so well that I bought them for my new truck. 2022 Chevy 3500 crew cab long bed. I use my truck to carry both my truck camper which is a Northstar 850SC or when I pull my 31-foot travel trailer.

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:

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:

I have a 28-foot-long class A motorhome on a Ford F53 Chassis. The handling of the vehicle at any speed above 50 mph is terrible. The vehicle wanders all over; very difficult to keep the vehicle between the lane marker lines. The SumoSprings, installed front and rear, did not solve this problem. Money would have been better spent elsewhere!



by:

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.



by:

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:

Installation hardware did no work for my F53 chassis



by:

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:

I installed these front Sumos on my 2023 Ford F53 chassis Class A Tiffin for several reasons. The factory bump stops had fallen out so something needed to be installed. I decided to invest in the Sumos to provide suspension support and get all the benefits of Sumos. I installed them, test drove the coach and am pleased with the results. They help cushion the front end and provide anti roll assistance. They work well with the Konis to soften the natural harshness of leaf springs. I’m very pleased with this addition.



by:

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.

  • Recommended Suspension Enhancement To Level A 2020 Chevy Silverado 2500 Out While Hauling A Trailer
    Hey John, If you're referring to the SuperSprings # SSA13MXKT you wouldn't really be getting much of an improvement over the RAS system since they operate the same way and both have similar capacities. Air springs would allow you tor adjust the height quite a bit more precisely but require a maintenance and you'd need an air compressor to adjust the psi levels. You could increase the capacity of your jounce springs to ones like the # SSR-203-47-2 but that could affect you unloaded ride...

  • Recommended SumoSprings Rear Helper Springs for 2022 Chevy Silverado 3500
    We have two options of SumoSprings for your 2022 Chevrolet Silverado 3500. The # SSR-203-40-2 is rated for 3,000 lb. capacity at 50% compression and the # SSR-203-47-2 is rated at 5,000 lb. capacity at 50% compression. The 3,000 lb. rated # SSR-203-40-2 are typically adequate for most and my recommendation needed for lighter towing or have light or mid-size fifth wheel trailers. If you need for heavier-duty application such as towing a larger 5th wheel or toy haulers, I suggest you...

If the trailer weighs 14,500 lbs then the pin weight is likely around 2,200 lbs. I'm sure the 3,000 lb option would be alright but you are...

  • Difference Between SumoSprings Rebel and Solo Suspension Kits for 2024 Chevy Silverado 2500
    Hey Justin, for your 2024 Chevy Silverado 2500 the big difference between the SumoSprings Solo part # SSR-207-47 and the Rebel part # SSR-203-40-2 is the weight capacity of either. The Solo can provide up to an additional 1,500 lbs of support and the Rebel 3,000 lbs so you'll get a lot more with the Rebel. So if you'll be towing a lot of weight closer to the capacity of the truck go with the Rebel but if you won't really get close to the capacity it would be better to go with the Solo....

  • How To Choose Correct SumoSprings Rebel Custom Helper Springs for 2021 Chevy Silverado 2500
    The SumoSprings Rebel Custom Helper Springs part # SSR-203-40-2 are what I recommend for a 2021 Chevrolet Silverado 2500. These springs will be great for all recreational towing jobs whereas the higher rated part # SSR-203-47-2 will be more geared towards constant work applications. The reason you just don't want to go with the highest rated options is because the higher rated springs are stiffer and will have a rougher ride when you rated for them.
