Features


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