What Our Customers Are Saying

Installed the black rear SumoSprings to help with towing my 25-ft boat. Before, the rear end sagged and felt bouncy over uneven roads. Now the truck stays level and stable, even on windy days. Ride quality is still smooth when unloaded, and installation only took about 45 minutes. Best suspension upgrade I’ve done.

Tyler James

Ford F-150 Lariat

After adding a bed rack, rooftop tent, and gear for overlanding, my Ranger sat low in the back and bottomed out on bigger hits. The yellow SumoSprings brought back the ride height and added control on rough trails. No more sway on the highway either. Install was easy, and I love not having to deal with air compressors or hoses.

Matt Reynolds

Ford Ranger FX4

I tow a 21-ft camper with my Expedition for family trips, and before SumoSprings, it always squatted and felt unsettled at speed. The blue SumoSprings made a huge difference — level stance, no more bouncing, and much better stability in crosswinds. Even without the trailer, the ride is comfortable and controlled. Highly recommend.
