Ride Comfort

SumoSprings absorb harsh bumps and jolts to provide a smooth ride over uneven surfaces, highway joints, and other rough terrain.

Driver Control

By reducing harsh movements, SumoSprings give drivers better control of their vehicle. This increases safety and makes for more comfortable travel.


SumoSprings have a progressive spring rate. They start to compress smoothly with less resistance and provide greater resistance as they compress further.


SumoSprings increase comfort and control, help stabilize sway, and level loads. This makes SumoSprings a unique and complete suspension solution.
