Rear Suspension Support

Towing or hauling a heavy load can cause rear 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 weight of your vehicle. 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 vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.


Installed spring when it is not compressed

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 closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.


Installed spring when it is compressed

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 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.


The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

  • Is There an Air Bag Kit for a 2024 Chevrolet Express 4500 Class C Motorhome?
    Hey Larry. I am sorry but there are no air bag kits for your 2024 Chevrolet Express 4500 class C motorhome. The closest alternative I have are the SumoSprings Solo Custom Helper Springs item # SSR-206-54. These replace your factory bump stops and help absorb road shock.

  • Recommended Suspension Enhancement for 2021 Chevrolet Express 4500 Cutaway Motorhome
    For front and rear suspension enhancement on a Chevrolet Express 4500 I recommend the SumoSprings Solo Custom Helper Springs # SSF-204-54 and # SSR-206-54. The SumoSprings will help absorb bumps and shocks as well as minimize sway and giving you a smoother ride overall. They have progressive load control and work independently to help reduce body roll and compensate for off-center loads.

  • SumoSprings For 2025 Jayco Redhawk 22C on Chevy 4500 Chassis
    Hey John! I reached out to SuperSprings for you, and the SumoSprings Solo Custom Helper Springs you’ll need for your 2025 Jayco Redhawk 22C is part # SSR-206-54. Just a quick heads-up—they wanted to make sure you know that this kit is only compatible with the 2WD version of the Chevy 4500 chassis. If your Redhawk is 2-wheel drive, you’re good to go! Let me know if you have any questions or need help confirming your setup—I’m happy to help!

  • Are There SumoSprings Available For The 2007 Forest River Sunseeker Workhorse 3500 Chassis?
    With your 2007 Forest River Sunseeker 2900 on the workhorse class C cutaway chassis you will need to use the Timbren # TGMRW55 if you are wanting to replace the factory jounce bumpers. SumoSprings does not offer a set of jounce bumpers for your chassis only SuperSprings # SSA39 to reduce sagging and improve stability. If your bump stop still does not match this please reply back with your images so I can verify what you have and find another option.

  • Suspension Enhancement Option For 2020 Chevy Express 4500 Cutaway Motorhome
    We do have an option for suspension enhancement for your motorhome on a 2020 Chevy Express 4500 cutaway chassis, but the SuperSprings SSA245-2 won't fit since you do not have the top overload spring, as they are designed to install on top of the spring. So instead, I recommend another option, which are SumoSprings, with the correct fit for your RV being the following: - Rear Axe: SumoSprings Solo Custom Helper Springs # SSR-206-54 - Front Axle: SumoSprings Solo Custom Helper Springs #...

  • Availability of Suspension Enhancement for 2015 Chevy Express 3500 Cutaway
    Since you were looking at the # AL55FJ I'm assuming you want to add suspension enhancement to your 2015 Express 3500 Cutaway. There is a difference between the cargo van and the cutaway. The cutaway isn't an option in the vehicle styles but we do call out the products that fit the cutaway in the installation notes. If you have a 159" wheelbase I recommend using the SumoSprings Solo Custom Helper Springs # SSR-206-54. These have a weight capacity of 2,800 lbs and will help absorb road...

  • Suspension Enhancement for 2018 Coachmen Freelander 27 Foot
    While we don't have air bag suspension enhancement that fits your 2018 Coachmen Freelander 27 foot motorhome we do have SumoSprings kits that fit like the # SSR-206-54 which will give you the stiffness and stability you are looking for to improve the ride quality. I attached an install video for this kit for you to check out as well.

  • Improving Rear Suspension Ride Quality On A 2005 Coachmen Freelander Class C Motorhome
    If your Coachmen Freelander 2330 RK Class C Motorhome with a Chevy Express 3500 cab and chassis has 4WD then I recommend the Timbren Rear Suspension Enhancement System # TGMRG35. Timbrens are known for causing a stiffer ride when the vehicle is unloaded but you can mitigate the stiffness by decreasing the spacers used during installation to allow for a larger gap between the Timbren and the axle. Another thing to consider is the weight capacity of the Timbren's; this option is 3,600lbs...

  • Suspension Enhancement Recommendation for 2011 Chevy Express Van 3500 Cutaway
    For your 2011 Chevy Express 3500 cutaway chassis we have the SuperSprings kit part # SSR-206-54 which will give you additional rear suspension support of 2,800 lbs. This will do a great job getting rid of the sag you are experiencing on the one side of the trailer and will also help with stability and handling as well.

  • Recommended Suspension Enhancement For 2018 Coachman Freelancer 27' W/ Chevrolet 4500 Chassis
    I have another option for you, but at this time there is not an air helper spring system confirmed to fit your 2018 Coachman Freelancer 27' built on the Chevrolet 4500 Van chassis. Instead I recommend adding the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-206-54 and Front # SSF-204-47 to your Freelancer as they will help support your suspension while carrying the weight of your RV, and help to minimize sway, absorb road shock, and are maintainence free.

  • Suspension Enhancement that Fits 2009 Freelander 2130
    We have great suspension enhancement that fits your 2009 Freelander 2130 like with the part # SSR-206-54 but there isn't a RAS system that fits your RV. The SumoSprings kits do offer similar support and ride quality as the rAS kits so this would be a great option.

  • Suspension Enhancement Recommendation for 2015 Chevrolet 3500 Express Cutaway
    We have suspension enhancement that is a fit for a 2015 Chevy Express 3500 on a cutaway chassis, but it's not the Firestone Kit part # F2700 that you referenced. Instead you would want the SumoSprings kit part # SSR-206-54 which is a confirmed fit. This is a rubber spring kit instead which means you still get the suspension support but you do not have to maintain air pressure or run any air lines.
