When you load up the bed or hitch on a heavy trailer, the factory suspension can squat and throw off your steering and braking. These SumoSprings helper springs add up to 1,500 lbs of support at 50-percent compression to level your ride and keep control steady. They help your rear suspension carry the extra weight and maintain even contact between your tires and the road so you tow and haul with confidence.
Whether you’re carrying tools, gear, or just driving unloaded, these springs adapt automatically. Their progressive design compresses softly for lighter loads and ramps up support as weight increases—up to 80 percent compression when fully loaded. The result is a smoother ride when empty and solid stability when you’re packed down or towing heavy.
When turns, side winds, or uneven cargo try to tilt your rig, each spring works on its own to even things out. That independent action helps reduce body roll and sway so your vehicle feels planted through corners and on rough roads. It also helps balance off-center loads so one side doesn’t sag more than the other.
These springs are made from microcellular urethane that resists oil, road salt, and UV damage while working in temperatures from -25°F to 200°F. They don’t need air pressure checks or tubing like air bags—just bolt them on with the included hardware and go. The two-piece design connects top and bottom for full suspension travel, keeping the unloaded ride comfortable without restricting movement.

Definitely less moving parts to worry about than airbags :) The install looks great! Are you hitched up in the photo to test out the springs or were you actually on your way to the water?

Cant believe its been a year since I installed the SumoSprings. Every time I go around a corner I so appreciate the excellent handling I now have. The Sumos have earned their 5th STAR!
