What Our Customers Are Saying

I converted my Transit into a full-time camper, and the added weight from cabinets, water tanks, and gear had it sagging in the rear. After installing the black SumoSprings, the van sits level, handles crosswinds better, and feels much more stable on mountain roads. Empty ride is still comfortable, and I haven’t had to touch them since installation.

Caleb Foster

Ford Transit High Roof

Our ProMaster is our rolling tiny home, and before SumoSprings, we’d bottom out on speed bumps and rough campsites. Now it’s smooth, level, and handles like a dream, even fully loaded. Install was quick, no air lines to fuss with, and they’ve made long drives far less fatiguing.

Olivia Reyes

Ram ProMaster 2500

My Sprinter build is heavy — solar, battery bank, full kitchen — and I do a lot of off-grid camping. SumoSprings eliminated the sway and lean I used to feel on twisty roads, and off-road washboards are much less punishing. It’s a set-it-and-forget-it upgrade I’d recommend to any van lifer.
