Class B Motorhome

What Our Customers Are Saying

Huge difference in driving quality between the stock bump stop and sumo springs. We went from bumpy ride and feeling every pot hole to better ride quality. Before the sumo springs every high wind areas we passed I have to slow down and manage the steering wheel continuously, After the install, it’s much stable and resists cross winds immediately and consistently adjusting the vehicle position in space. Probably the best investment I put on our 2020 Airstream Interstate 19.

When my wife and I head out in our 2023 Winnebago View we are looking for the best ride we can get. I don’t like swaying back and forth in crosswinds or leaning in turns. And we try to miss every big bump in the road but that is not always possible. After 18 years and 2 Sprinter Class C motorhomes without doing any suspension upgrades, we decided to try front and back SumoSprings. I chose the blue front and black rear SumoSprings and Wow! they give the RV a more “planted” feel and a better ride without increased road noise or stiffness. I would absolutely buy them again. They have increased our confidence a lot. My goal is to have a motorhome that drives more like an SUV. The SumoSprings along with new rear Fox shocks have given us a much improved ride. We now feel more relaxed when driving in cross winds and I can’t describe how much better it feels to turn without leaning. Happy driving, hope you enjoy the road as much as we do.

Since we own a 2022 Travato 59K, the Super Springs lifted the generator approximately 3/4 inch above the rear axle. Before the generator was hanging approximately 3/8 inch below the rear axle. They also improve the ride – less sway and better handling. This is in addition to the yellow SumoSprings.
