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-315-47-2 has a 5,000 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.

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 bought these to get nose of my truck down when towing 25 foot gooseneck. I load heavy hauling lumber. The SumoSprings work great.

Outstanding! Just pulled my trailer for the first time with the springs and it was a 100% improvement in handling.
