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-139-40-2 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.

Note for lifted trucks: A Spacer Kit may be be required to install this product. Please chat with our team here to see if your particular set up requires this kit before purchasing.
