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-121-54 has a 2,800 lb capacity when compressed at 50%. The Yellow SumoSprings shouldn’t be compressed past 55% of their original height in order to keep full memory rebound.

Really satisfied by the quality and the design of your product. Complet installation as been done in 1 hours and a half without using any specialized tools. And the results is amazing. I drove a truck loaded with tools for a service company. This is exactly what my truck needed. Thanks again for your hard work and for your great service.

Installation was easy and straight forward. I really appreciated that everything was included- including the thread lock. Driving the van, it is noticeably more stable and much more controlled in corners. Not as susceptible to wind sway. Very pleased!
