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-312-47 has a 1,500 lb capacity when compressed at 50%. The Black SumoSprings shouldn’t be compressed past 65% of their original height in order to keep full memory rebound.

They were very easy to install.

Easy to install; looking forward to our first towing experience with them installed in June.

When I put a 1700 dry weight camper on the truck with stock off road suspension there was at times an uncomfortable amount of sway and porpoising. The Sumo springs, 800# in front and 1500# in the rear, resolved the issue. Very pleased.
