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-117-40 has a 1,000 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.

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.

Easy installation and boy have I noticed a difference already. I will recommend this product to anyone who hauls or tows.

I am a rural vet and have a truck with an 8ft bed with an 8ft vet box with a tank of water and all my equipment. It weighs down the back of my truck. We bought the sumo springs to help with the weight load of the back. Holy cow, I could tell a huge difference the first time I drove it after installing. Installing was very easy. I can't wait to tell my fellow vets who have boxes in the back of the truck. World of difference!
