What Our Customers Are Saying

I tow a 27-ft enclosed trailer for work and was getting way too much rear squat. Installed the black SumoSprings and it’s a completely different truck — level stance, smoother ride, and way less sway in crosswinds. Unloaded ride is still comfortable, and the install was a simple afternoon project.

Chris Dalton

Chevrolet Silverado 1500

I haul heavy equipment almost daily, and my Sierra would bounce and bottom out over rough roads. The yellow SumoSprings have eliminated that problem completely. The truck now feels planted and stable no matter the load. Even when empty, the ride is still smooth. One of the best upgrades I’ve made for towing and hauling.

Daniel Ortiz

GMC Sierra 2500HD

Pulling a large fifth wheel used to mean a lot of rear sag and some uncomfortable sway on the highway. The SumoSprings fixed both instantly — now it tows level, stable, and feels far more controlled. Install took just over an hour, and there’s nothing to maintain. Wish I’d added these sooner.
