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-100-40 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.

So far I’m loving the upgrade from my factory hard bump stops!
Put the sumo springs builder kit on my 1999 Camaro SS as I live down a dirt road and have very poorly constructed roads in my area. After redoing the entire suspension on the car and still getting tossed around I decided to try the sumo springs bump stops. The sumo springs have made a world of a difference when driving down the dirt drive way as well as down the poor public roads in my area. My car no longer bottoms out or makes a loud bang noise when hitting some of the bumpy areas. To put them on the car I had to design a custom bracket in the shop.
