With a cord of wood loaded in your payload and a burly winch strapped 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 2-year warranty.

I put these on to fix clunking on the up travel of my cranked Silverado. They work amazing, my truck is quiet as a mouse now. But the gm engineers put tabs where the bumpstops are..took some work to get them in but I also didn't take off the wheel.. well worth it for sure. They help close the bumpstop gap on a tb cranked front end since they are an inch longer than stock

Haven't had it out in the wind yet but they do seem to stabilize the ride a bit more without making it stiff or harsh. Read lots of positive reviews and have had the rears installed for 1.5 years. Figured it was time for the fronts.

I never thought this would work well. But I was wrong. My truck stays much level in the turns. Firm but not stiff and bouncy. Because they are in constant contact with the axle, my FOX shocks do not need to work as hard.

The Sumosprings where so easy to install. The interior noise level in the motorhome dropped by 50%. It handled beyond my expectations. With just the back springs installed, it did not sway in the wind, corners, or driveways. It drove like a pickup truck. I am most impressed. I just bought the Sumosprings for the front.
