Towing or hauling heavy gear can make the rear end sag and throw off your handling. These SumoSprings Solo helper springs add up to 2,800 lbs of support at 50-percent compression so your ride stays level and controlled. They help your factory suspension bear the load, keeping steering and braking steady and eliminating that droopy stance when you’re hooked up or loaded down.
When the road gets bumpy, these microcellular urethane springs cushion the impact so your ride doesn’t feel harsh. They compress easily with lighter loads for a softer ride, then stiffen as the weight increases—up to 80 percent compression—to give the support you need without bottoming out. You get smooth engagement when lightly loaded and solid control when the truck’s working hard.
Each SumoSpring works on its own side, helping to even out off-center loads and cut down on body roll. When you hit a curve or get blasted by a crosswind, this independent action keeps both sides stable so your truck feels planted through turns and uneven ground.
Forget air lines, fittings, or pressure checks—these springs are completely maintenance-free. The closed-cell urethane resists oils, road salts, and UV damage while performing in temperatures from -25 F to 200 F. They mount right in place of the factory bump stops with no drilling required, so installation is simple and clean without extra parts to adjust later.

We cover the warranties on the majority of the products that we carry. There are manufacturers who prefer to handle the warranties directly with the end purchaser of the products. They are able to provide a faster solution this way.

Glad to hear the install wasn't too bad, Michael! Definitely let us know how the ride is once you take it out for a drive! What are you using your Van for? The tires look pretty beefy.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?

Thanks for the awesome feedback, Jeff! Love hearing that the install was a breeze and that you noticed such a big difference in handling, that’s exactly what you want after the upgrade. Really appreciate you sharing the photos too, it’s always fun to see the comparison.

The springs are working exactly as expect. I have need up to the mountains numerous times and to Monerary to the Sea Otter bike fest. They have reduced the body roll and helped keep the truck stable on the mountain roads or when loaded down for camping. Im very pleased I added these Sumo Springs to my Tacoma.

Glad to hear they are helping, Cory! If you are feeling them going over speed bumps, I think taking one of the spacers out is a good idea. Especially if that is happening when you are unloaded. Speaking of which, what are you towing?

I am sorry to hear that this item is not working properly for you. I see that this manufacturer prefers to handle all of their own warranties. I have sent your information over to the manufacturer for them to get in touch with you about a possible warranty.
