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-315-40-2 has a 3,000 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.

Note for lifted trucks: A Spacer Kit may be be required to install this product. Please chat with our team here to see if your particular set up requires this kit before purchasing.

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.

I was concerned about the "proposing" effect while traveling with our travel trailer. I very pleased with the Sumo Springs! They eliminated at least 70% of the "proposing"!

If I could go higher than a 10 I would. I rarely give 10s but in this case, absolutely awesome service. Had an issue and they bent over backwards to make it good. I truly appreciate service like that. Thank you Mark for all your help.
