SuperSprings TSS-107-40 Pair of Left and Right Trailer SumoSprings | GAWR of 3,000-5,000 lbs | Reduces G-force in Trailer by 68% | Removes Sway, Hop and Body Roll

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.
