Heavy front-end gear can cause sag that throws off steering and braking. These SumoSprings Solo helper springs add up to 1,200 lbs of support at 50-percent compression to level your ride and steady your handling. They take pressure off the factory suspension so the front stays planted, traction stays even, and steering feels predictable with or without extra weight.
Road bumps and potholes don’t have to shake the cab. The microcellular urethane springs compress easily under light loads for a soft, comfortable ride, then firm up as weight increases—up to 80 percent compression under heavy load. This progressive rate keeps the ride smooth when empty and controlled when loaded, so you can drive through rough pavement or uneven terrain without harsh jolts.
When a curve or gust of wind pushes you off balance, these springs work independently on each side to keep the vehicle steady. That means less body roll in corners, less rocking when pulling into uneven driveways, and a more controlled feel in highway crosswinds.
Each spring is made from durable microcellular urethane that resists abrasion, oil, salt, and UV damage. It performs in temperatures from -25 F to 200 F and compresses vertically with minimal side expansion so it won’t rub against nearby parts. There’s no tubing to run or air pressure to check—just a set of maintenance-free springs that you can count on every time you hit the road.
Adding front-end support shouldn’t mean a long day in the shop. These custom-fit jounce-style springs bolt in easily using existing mounting points—no drilling required. In one afternoon with hand tools, you can have dependable suspension support ready for every haul or trip ahead.

Appreciate you leaving a review Austin, It's always nice when a product exceeds expectations and these springs have been highly rated. Are you typically off road or do you plan on towing?

30 Minutes for all 4?! That's got to be some kind of record, Dennis! Glad the process was nice and easy and I hope they serve you well. Let us know if you do end up needing to go to the heavier duty yellow option as well, we always like to get real life experiences from people. : ) Any more trips planned for the year?

That is awesome to hear! It must be such a relief to not have to put so much energy into controlling the wheel while driving now.

Oh no! That is definitely not normal for these. Would you be able to clarify what you mean by busted? How heavy would you say your load was? I am noticing these are light duty and wonder if they were over loaded by mistake?
