Trailer SumoSprings; Capacity 500 lbs. At 50 Percent Compression; For Spring-Over Axle Configuration;
Trailer SumoSprings(R) 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's, and other components by minimizing bounce, hop, and sway associated with most tow-able 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.
