“I put SumoSprings on my F-150 after getting tired of the rear end sagging every time I hooked up my camper. The install was quick, and the difference was immediate. The truck stays level now, handles better in crosswinds, and I feel way more confident towing. Honestly, it’s one of the best upgrades I’ve made to my truck.

We travel a lot in our Class A motorhome, and rough roads plus heavy crosswinds used to make driving stressful. After installing SumoSprings Maxim, the difference has been incredible. The coach feels more planted, the ride is smoother, and I don’t get as fatigued after long days behind the wheel. For anyone with a big RV, this is hands down the upgrade you didn’t know you needed.

I added Coil SumoSprings to my Jeep Wrangler for off-road trips, and I can’t believe how much better it feels. On the trail, the sway is reduced and the ride is way more controlled. But what surprised me most is how much smoother it drives on the highway too. It’s rare to find a mod that works this well both on and off road — these absolutely nailed it.
