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.


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.

  • Recommended Suspension Support That Is Not Air Bags for a 2024 Ford F-350
    Hey Kent, thanks for the information. If your 2024 Ford F-350 is a 4WD model, I recommend the SumoSprings Rebel Custom Helper Springs item # SSR-128-40-2. These have a 3,000 lbs leveling capacity and replace your factory bump stops. The springs have a two piece design so unless you put weight on the rear end of your truck they will not engage. You're not squatting that much so these will do a great job of maintaining your daily driving ride quality while also keeping your rear end level...

  • Comparing The Solo And Rebel SumoSprings Options For 2022 Ford F-350 Super Duty
    Between the SumoSprings Solo Custom Helper Springs # SSR-127-54 and the SumoSprings Rebel Custom Helper Springs # SSR-128-40-2, I do prefer the Rebel. 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. I also like...

Also, the design is a bit different. Where the Solo Custom Helper Springs are a one-piece design, the Rebel Springs are a two-piece design that is separated in the middle that allows for unlimited suspension travel. One piece attaches to the frame of the truck, and the other attaches to the...

  • Timbren vs SumoSprings for 5th Wheel Towing with a 2022 Ford F-350 Super Duty 4x4
    I definitely understand the confusion, as both kits look similar. 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...

  • Weight Distribution Hitch for 6,000 lb Travel Trailer and Will SumoSprings Reduce Tongue Weight
    SumoSprings will not affect the tongue weight for the weight distribution hitch, and I can help you decide the best hitch. In order to choose the best weight distribution system you will first need to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go trailer plus the weight of any cargo behind the rear axle of your F-150. The tongue weight is typically between 10% and 15% of your trailer's GVWR but you'll want to verify it by using a...
