Heavy trailers and bed loads can make the rear of your ride sag, throwing off your steering and braking. These SumoSprings Solo helper springs add up to 1,500 lbs of support at 50-percent compression to help level things out and keep the truck steady under load. They cushion bumps, absorb shocks, and share the weight with your factory suspension so the front tires stay planted on the road for better control and traction.
Whether you’re towing a camper or running empty, the springs adjust automatically to match the weight. Light loads compress the springs easily for a softer ride, while heavy loads engage more of the spring for firm support. This progressive design keeps small bumps comfortable and big hits under control without the harsh rebound that stiffer systems can cause.
Each spring works on its own side of the vehicle to handle uneven weight or off-center loads. When you round a turn or a crosswind pushes against you, this independent action helps reduce body roll and sway. That means steadier handling through curves, better balance when you’re loaded unevenly, and a more planted feel on the highway.
Made from durable microcellular urethane, these springs stand up to temperatures from -25 F to 200 F and resist damage from oils, road salts, and UV rays. They compress vertically with minimal side expansion so nearby parts stay safe even in tight spaces. Unlike air systems, they’re completely maintenance-free—no airlines, compressors, or pressure checks to worry about—and they install easily with no drilling required.
