Heavy trailers or bed loads can make the rear of your vehicle sag, throwing off your handling and braking. These SumoSprings helper springs add up to 1,500 lbs of support at 50-percent compression to keep your ride level and controlled. They help your factory suspension carry the extra weight so your steering stays steady and your headlights stay aimed where they should.
You don’t need to give up comfort to get support. The microcellular urethane springs compress easily at first for a soft, cushioned feel on lighter loads, then stiffen progressively as weight increases. That smooth, progressive action helps absorb bumps and shocks so the ride stays comfortable whether you’re carrying a few tools or hauling a full load.
When a curve or passing semi tries to push you around, each spring works independently to keep both sides planted. This reduces body roll and sway so your vehicle feels stable through turns or uneven ground. Even off-center loads won’t throw off your balance—the springs help even things out automatically.
These durable microcellular urethane springs hold up in temperatures from -25 F to 200 F and resist oil, road salt, and UV damage. They compress vertically with minimal side expansion, fitting safely in tight spaces without interference. There’s no air pressure to monitor or tubing to run—just install them with the simple no-drill setup and hit the road knowing they’ll keep working trip after trip.

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.

Thanks for the awesome feedback, Jeff! Love hearing that the install was a breeze and that you noticed such a big difference in handling, that’s exactly what you want after the upgrade. Really appreciate you sharing the photos too, it’s always fun to see the comparison.
