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.
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.
