What does it take to install a set of Sumo Springs in your Jeep? Check out our DIY video here: Jeep Sumo Springs Install
SumoSprings® are a patented suspension product designed to enhance load carrying ability, stabilize sway, and improve overall driver control and ride comfort. They are maintenance free, do not leak air, and do not require airlines or compressors.

These heavy duty bump stops install directly into the JK coil bucket and prevent the suspension from bottoming out through the last few inches of travel.
Whether dropping off of a rock ledge or hitting the whoops, the factory bump stops can not effectively keep up with the force that is being exerted on them.
