With a cord of wood loaded in your payload and a burly winch strapped to the front bumper, your workhorse starts to sag like a twenty-year-old mattress. In the past, you'd have to rig up a complicated airbag system with hoses and compressors that need constant attention. Now, bolstering your suspension is a cinch with SumoSprings, the world's first "airless airbags".

The mad scientists over at SuperSprings cooked up a cutting-edge formula of closed-cell polyurethane foam and heavy-duty additives to form the spine of your springs. This blend gives your Sumo Springs the ability to compress up to 80% and expand up to 20%, delivering a progressive spring rate. Whether you're hauling a pile of bricks or a six-pack of chubby wrestlers, SumoSprings deliver exceptional ride quality with zero maintenance needed.

Custom engineered for a perfect fit, SumoSprings are available for the front and rear of your pickup, SUV or van. They're sturdy enough to handle harsh conditions, and most bolt directly into place with no drilling needed. Plus, they're backed by a limited lifetime warranty.
