Rear SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to reduce rear-end sag and increase load carrying ability while decreasing vibration, stabilizing sway, and softening harsh rebounds. 

The SSR-187-40-1 has a 3,000 lb capacity when compressed at 50%. The Blue SumoSprings shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.

Sumo Springs made a huge difference in the side to side sway and control of the coach. They also improved the ride.
