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.

I did front and rear sumo springs. Since I only tow a trailer about 60 days a year i didn't want something that would compromise the ride the other 300 days a year. Dare I say it made the overall ride better because as a nice side benefit it seems to reduce body sway in turn. Use large pliers for leverage to twist them out. You also need a blunt pry bar to installation. You'll need an assistant too

If you're thinking about purchasing this product do it!! It is everything it is build up to be. Installation takes less than 30 minutes and that was taking my time. I hauling 9000 pound trailer and now my truck only dips 1 inch. I have a slightly stiff ride without the trailer but nothing objectionable. The product seems to be well-made. I would definitely recommend it to anyone who wants to maintain ride height and stability. They shipped it fast and the price was the best I could find.

I have had sumo springs on my last 3 truck. I love them and they work great. This truck has the 5000 lb rated sumo springs, which are a little stiff, but I drive a truck not a Cadillac. They help control the porpoising when towing and eliminate a lot of the sag from my heavy goose neck trailer. Install was a pain because they fit a little tight, but other than that I highly recommend them.
