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.

  • Best SumoSprings For 2021 Ram 3500 Towing 5th Wheel Trailer
    Sag is a pretty common problem for trucks towing a 5th wheel trailer, so SumoSprings are a smart idea, and the best option for your 2021 Ram 3500 are the following: - SumoSprings Rebel Custom Helper Springs # SSR-301-47-2 The SumoSprings # SSR-301-47-2 have a 5,000 lb capacity to give your '21 Ram the support it needs when towing. These are going to engage only when you are towing (or otherwise have a heavy load in your Ram's truck bed) so your unloaded ride won't be affected. But when...

  • Best Suspension Enhancement for 2016 Ram 3500 to Improve Ride Quality
    Hey BZ, the best suspension enhancement option we have for your 2016 Ram 3500 that will improve loaded an unloaded ride quality is the Roadactive part # RAS3613-HD. This is only kit where all of the feedback we have gotten on it has been that it has improved ride quality. SumoSprings aren't terrible but the reaction isn't usually as positive as the RAS kits.

  • Recommended Suspension Enhancement for a 2021 Ram 3500 SRW
    The Timbren item # TDR3500CA is the same as the DR3500CA and is confirmed to fit your 2021 Ram 3500. I would stay as far away from Timbren's as possible unless you're towing with a work truck. They will make for an extremely unpleasant and stiff ride when you are not towing your trailer. Your tongue weight won't be anywhere near their maximum capacity and you will feel them on every bump. Instead I recommend the SumoSprings Rebel Custom Helper Springs item # SSR-301-40-2. This system has...

  • Timbrens For 2020 Ram 1500 With Rear Sag Towing Heavier Fifth Wheel Trailer
    There is a Timbren Rear Suspension Enhancement System that is compatible with the 2020 Ram 1500 4WD with part # TDR1500DQ as confirmed by Timbren. Since you are experiencing rear sag I do recommend to use the Timbrens because they are the best option to reduce the sag. They are made of a dense rubber material that increases the stability of the suspension when hauling heavier loads. They also act as a shock absorber to extend the life of your suspension. The SumoSprings Rebel Springs that...

  • Helper Springs to Reduce Rear End Sway on a 2015 Ram 3500 with Slide-In Camper or 5th Wheel Trailer
    If you are looking for the best option to help with sway while also providing additional support that will not affect the ride when empty then I recommend the SuperSprings suspension stabilizer system, # SSA23. For your particular needs this would be the option I would choose. The SumoSprings Rebel system, # SSR-301-40-2, would be the better solution if you were looking for more support from a load that caused the rear of the vehicle to sag. This system is more likely to affect the empty...

  • Will A Rear Anti-Sway Bar Help With Wheel Hop When Hitting A Bad Bump In The Road
    An anti-sway bar like the Roadmaster Rear Anti-Sway Bar # RM-1129-144 will help with control when you hit a bad bump in the road, but it's more for strengthening the frame to prevent side to side sway. For wheel hopping you'd want to install the SumoSprings Rebel Custom Helper Springs # SSR-301-40-2. These springs are designed to absorb road shock and help prevent sag from hauling heavy loads. They're completely maintenance free so once they're installed you won't have any upkeep to worry...

  • Suspension Enhancement for a 2012 Dodge Ram 3500 Cab and Chassis
    The SumoSprings Rebel Custom Helper Springs, # SSR-301-40-2, that you have referenced is my top choice. These springs will replace the factory jounce bumpers. They are larger and will work much better than the factory jounce bumper. However, there is a chance that this will not solve the problem. I recommend inspecting the suspension on your truck to determine if something is broken and causing the sound. You cannot install suspension enhancement unless the vehicle suspension is in good...
