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-106-47 is designed for trailer frames with a GAWR of 5,000-8,000 lbs with the spring sitting underneath the axle tube. The Black SumoSprings shouldn’t be compressed past 65% of their original height in order to keep full memory rebound.

NOTE:
This product is designed to work on most trailers with the springs mounted below the axle.  Because of the varying build designs from different trailer manufacturers, there are occasionally some models that this product will not fit. For installation of Trailer SumoSprings the gap between the top of the leaf spring and bottom of the frame must be between 7.4″ and 8.65″.
