A heavy rear load can make your vehicle sag and throw off steering and braking. These SumoSprings Solo helper springs add up to 1,000 lbs of support at 50-percent compression to help keep your ride level and stable. They work alongside your factory suspension to handle the extra weight, so your vehicle stays balanced and your headlights stay aimed where they should.
Every load rides differently, but these microcellular urethane springs adjust automatically. With lighter loads, they compress easily for softer engagement and a comfortable ride over bumps. As weight increases, they compress by as much as 80 percent to deliver firm support that reduces sway and bottoming out. The result is smooth control whether you’re hauling light gear or towing something heavy.
When turns or uneven cargo shift weight to one side, each SumoSpring works on its own to balance the load. This independent action helps cut down on body roll and sway so the vehicle feels more planted through curves, crosswinds, or uneven driveways. Off-center loads stay manageable and steering feels more consistent.
These high-density microcellular urethane springs are built to take abuse from rough roads and harsh weather. They resist oils, road salts, and UV damage while performing in temperatures from -25 F to 200 F. With minimal lateral expansion, they compress straight up and down to fit tight spots without rubbing against nearby parts.
Installation is straightforward with no drilling required—just replace your existing bump stops with the included jounce-style springs. There’s no air pressure to monitor or lines to run. Once installed, they’re maintenance-free so you can focus on the road instead of the hardware under it.
SumoSprings will not increase your vehicle's weight-carrying capacity.
