Heavy front loads like slide-outs or cargo can cause sag and throw off steering control. These SumoSprings Rebel Custom Helper Springs deliver up to 3,000 lbs of support at 50-percent compression to keep your ride level and balanced. They work with your factory suspension to smooth out bumps, absorb shock, and help maintain proper headlight aim and traction for safer handling when loaded.
The 2-piece spring setup connects at the top and bottom but separates when unloaded, allowing full suspension travel for a comfortable ride on rough terrain. When weight is added, the pieces come together to add firm support. This design keeps the suspension flexible when empty while still providing solid front-end stability when carrying heavy loads.
These springs automatically adjust stiffness as you add weight. Light loads compress softly for smooth engagement and a comfortable ride, while heavier loads push them up to 80 percent compression for strong support. The result is a steady, predictable feel whether you’re driving light or fully loaded.
Each spring works independently to balance uneven loads and reduce body roll in sharp turns or side winds. That means better cornering control and less rocking when pulling into uneven spots or during quick steering inputs.
Made from durable microcellular urethane, these springs resist abrasion, oils, road salts, and UV rays while performing in temperatures from -25 F to 200 F. They expand and compress vertically with minimal sideways movement so nearby components stay safe. The kit includes two jounce-style springs with hardware for easy bolt-on installation and needs no air pressure or maintenance once installed.

After a year of driving 3500 miles with the Sumo Springs on the front of my 2005 Georgie Boy class A motor home I am somewhat disappointed. Yes they where easy to install. Yes they did help with body roll in a turn. But my issue is they did not help much with the violent bump when hitting potholes or bridge to road transitions on the major highways. I was hoping to get a much smother ride. And yes all the factory shocks have been replaced with Koni shocks.
