When heavy cargo or a trailer pushes down the back end, steering and braking can feel off. These SumoSprings helper springs add up to 1,000 lbs of support at 50-percent compression to keep your ride level and steady. They help your factory suspension handle the extra weight so your front tires stay planted, headlight aim stays true, and handling feels confident even on long hauls.
Not every haul weighs the same. These microcellular urethane springs use progressive load control to match the weight you’re carrying. With lighter loads they compress easily for soft engagement and a smoother ride, while heavier loads make them firm up for stronger support. The result is a balanced ride that absorbs bumps and keeps sway in check without needing adjustments or maintenance.
When corners, crosswinds, or off-center loads try to throw you around, each spring works on its own to keep its side of the vehicle steady. That independent action helps reduce body roll in sharp turns and keeps things level even when one side carries more weight than the other. You’ll feel more control through curves and less rocking when pulling into uneven driveways or job sites.
These springs are made from high-density microcellular urethane that stands up to harsh conditions. They resist abrasion, oils, road salts, and UV rays, and they perform in temperatures from -25 F to 200 F. Because they compress vertically with minimal side expansion, they fit tight spaces without rubbing nearby parts. And since there’s no air pressure to check or lines to run, they stay maintenance-free once installed.
Adding suspension support shouldn’t mean tearing the truck apart. This kit includes two jounce-style springs that install with a simple no-drill setup using existing mounting points. Once in place, you’re ready for a more stable ride without spending time managing air lines or fine-tuning adjustments.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?

Glad to hear the install wasn't too bad, Michael! Definitely let us know how the ride is once you take it out for a drive! What are you using your Van for? The tires look pretty beefy.
