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-312-54 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.

I pull a Grand Design 29rs Fifth Wheel and the pull with the Cummins Diesel has been wonderful since I added the Supersprings. Thank You Super Springs!
I ordered the direct replacement bump stop for my service truck and it raised the rear sag it had and going down the road the body doesn't roll and sway very smooth and easy install. will be ordering for my other trucks.
Fast shipping, well made and simple to install
