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.
Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.

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.
