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.

  • Recommended Helper Springs For A 2020 Jeep Gladiator With A 2 Inch Lift
    When it comes to installing helper springs on your 2020 Jeep Gladiator with a 2 inch lift I recommend The Timbren Rear Suspension Enhancement System # T76FR. This system has a 3,000 pound capacity and sit above the rear axle to help stabilize and level your Jeep Gladiator. You will also get a better ride because they absorb road shock and improve roll stability. They're easy to install and use. The spring work independently - side-to-side, and help compensate for off-center loads. Make...

  • Suspension Enhancement Recommendation for 2021 Jeep Gladiator Towing Trailer
    I would go with the SumoSprings kit part # SS42XR for your 2021 Jeep Gladiator Mojave for suspension support. Air bags can work great but they are a lot more maintenance and the support they provide is very easily pretty harsh. The SumoSprings kit is something that once you install it you don't have to think about it again and it will provide the support you are looking for for all of your trailers.

  • Recommended SumoSpring Jounce Springs For A 2021 Jeep Gladiator Rubicon
    Hey Erwin, I always recommend matching the enhancement to the weight you plan on towing while also factoring in your vehicle's payload capacity to avoid affecting your unloaded ride quality. With the payload capacity of your Gladiator being only 1,200lbs and the camper weighing in at 1,000lbs the SumoSprings Solo Custom Helper Springs # SS42XR (1,400lb capacity) would be more than enough to help support your suspension with the camper loaded in without being so stiff that it becomes uncomfortable....

  • Recommended Suspension Enhancement To Prevent Sag On A 2023 Jeep Gladiator
    For your 2023 Jeep Gladiator we recommend the SumoSprings Solo Custom Helper Springs # SS42XR. These are 1,400 lb capacity urethane springs. I prefer these over other options for a few reasons. Firstly because they will be a very easy bolt-on install. I also like the Sumo Springs because they feature Progressive load control. Meaning the spring becomes more firm as more weight is applied. So it will help keep your ride level and absorb shock when you are towing, and it will also allow you...

  • Recommended SumoSprings for a 2020 Jeep Gladiator
    For your 2020 Jeep Gladiator, I recommend the Blue SumoSprings Solo Custom Helper Springs item # SS42XR. These have a 1,400 lbs capacity and only engage when weight is placed on the rear suspension. These springs use a system called progressive load control. The more weight you place on them the more they engage. This provides you with only the support you need when you need it. Unlike other systems like Timbren's which negatively affect your ride quality whether or not you have a heavy...
