Rear Sumo Springs 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 Rear Helper Spring has a 3,000 lb capacity when compressed at 50%. The Blue Sumo Springs shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.
