Fits 16-18K GVWR Fleetwood, Forrest River, Newmar, & Thor Only
SumoSprings complement the original factory suspension by generating a smoother ride in your coach, and adding 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, 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.
