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-120-54 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.

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.

Put them on a Super C motorhome. Easy to install and has dampened the sharpness of impacts on Colorado pothole filled roads. Cabin seems quieter while travelling. Can't wait to take a longer trip to how they perform.

We have only driven to the gas station to fill up for our next trip but can already tell they are going to help.
