Super Springs TSS-107-40 Helper Spring Kit; SumoSprings; Air Spring; Blue; Trail

Trailer SumoSprings ® utilize the same micro-cellular air springs as SumoSprings. They mount above trailer leaf spring assemblies and create a cushion between the axle and trailer frame. Trailer SumoSprings reduce wear and tear on body-frames, windows, doors, closets, mounted tv, and other components by minimizing bounce, hop, and sway associated with most towable RV's. Reduced sway and bounce in the trailer results in increased driver control, ride comfort, reduced maintenance costs, and reduced overall cost of trailer ownership.
