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-203-40-2 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.

Received springs pretty quick. Mounting went ok except emergency brake cable on right side was fastened in the way to install j-hook

A little tricky with the install. Rear brake line RR in conflict with hook bracket. RL brake line passes over studs and nuts, friction on brake line a concern. Extremely happy with product. Used with cab over camper. Camper remodel at Grasslands, BLM areas, and forest roads. 4WD accessible public lands. Sumos made a big difference on washboard and rough roads, road haves and reasonable sway situations. I called and spoke to a friendly and knowledgeable salesman and followed his recommendations. I'm very glad I did.
