Trailer SumoSprings are a maintenance-free suspension enhancement built to create a better journey by reducing G-force in your towable by 68%. Handmade from micro-cellular polyurethane, they are designed to remove sway, hop, & body roll while increasing overall driver control and comfort while towing.
The TSS-106-40 is designed for trailer frames with a GAWR of 3,000-5,000 lbs with the spring sitting underneath the axle tube. The Blue SumoSprings shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.
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 TVs, and other components by minimizing bounce, hop, and sway associated with most tow-able RVs. Reduced sway and bounce in the trailer results in increased driver control, ride comfort, reduced maintenance costs, and reduced overall cost of trailer ownership.

Because of the varying build designs from different trailer manufacturers, there are occasionally some models that this product will not fit.
