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.

Installed my SumoSprings in about 30 mins. really simple to install on my 2018 Colorado Z71, once I realized that I didn't even need to remove the factory bump stops ??. I quickly put them to work by hauling a full load 4 passengers & (2 yards of damp mulch) and the truck only dropped about 2" and the ride was amazing. Bumps and turns were no problem, even went over rough rail road tracks with ease and smoothly. Well worth the money!!! Best mod. yet! Definitely need this if you tow or haul!

Installed the Sumo Springs without any issues. Took less than an hour with the correct tools and jacks. have not had the chance to test with the camper on yet but happy how quickly they arrived and ease of installation.

I was a little skeptical at first but they came through with no problems. The installation was easy and they look great over the stock ones. The back end of the truck handles the roads better for hauling and for towing everything. The sumo springs product is great and at value costs savings over air bags. I do recommend this product to everyone.
