What Our Customers Are Saying

After adding SumoSprings to our Thor Axis, the difference was night and day. Before, every bump and gust of wind felt like a battle to keep control of the coach. Now the ride is smoother, cornering feels tighter, and crosswinds aren’t nearly as stressful. I actually look forward to long driving days now instead of dreading them. Best upgrade we’ve made to our motorhome.

Karen Whitfield

2021 Thor Axis (Class A)

Installing SumoSprings front and rear was a game changer. The constant rocking and swaying is gone, and the ride feels solid without being harsh. My wife used to get nervous every time a semi passed us on the highway — now the coach stays steady and recovers instantly. Feels like I’m driving a different motorhome altogether.

Mark Stevenson

2019 Jayco Greyhawk (Class C)

Our Boldt went from feeling like a delivery van to driving more like a luxury SUV. The suspension upgrades cut down on sway, reduced body roll in curves, and made the entire cabin quieter on rough roads. Honestly, I didn’t realize how much stress came from fighting the steering wheel until it was gone. SumoSprings are worth every penny for peace of mind and comfort.
