Rear Sumo Springs F-53 Chassis 16-18k GVWR, 1990-2004
Rear Sumo Springs F-53 chassis 16-18k complement the original factory suspension by generating a smoother ride in your coach. They also add more stability. These variable rate springs improve load carrying capacity. Due to their proprietary material, they function much like a shock absorber by insulating the “banging and jarring” effect resulting from impact with pot-holes, road expansion joints, uneven road surfaces, and bridge on-ramps, etc. Additionally, their constant engagement will reduce the amount of side-to-side body roll in your coach, which results in greater stability.
