Featured Part: SumoSprings®

SumoSprings® are a patented suspension product designed to enhance load carrying capacity, stabilize sway, and improve overall driver control and ride comfort. They are maintenance-free, do not leak air, and do not require airlines or compressors. SumoSprings® are manufactured in a variety of heights, dimensions, and densities to support multiple front and rear applications. They are manufactured from a proprietary closed-cell micro-cellular urethane providing a smooth and progressive spring rate.

SumoSprings Features:

  • Shock absorption – superior dampening properties, ultimately reducing wear and tear
  • Sway control – reduce sway by 30%
  • Load support – progressive spring rate helps level varying loads
  • Maintenance-Free – Fit it and forget it
  • Leak-Proof – No leaks, ever
  • Reduce ownership costs – reduced wear and tear equals lower ownership costs

SumoSprings can be added to the ProMaster, Ford Transit, and Mercedes-Benz Sprinter chassis.
