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.
SumoSprings Builder Kits are meant for use on custom applications and can be mounted in a variety of ways either on the front or the rear of the vehicle.
Each customer will need to supply their own hardware and bracketry for the installation. We recommend using Grade 8, 3/8 hardware or similar.
The SFR-100-54 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.

Brand Protection continues to be of the utmost importance for our company and our customers. We’ve spent the last several years building and rolling out processes to that end.
With that in mind, effective immediately, we’ve added Amazon to our Do Not Sell list.
Please make sure you frequently review the Authorized and Unauthorized Sellers on below to ensure your adherence to our Brand Protection Program. Selling to an Unauthorized Seller violates that program.
