Class C Motorhome

Class C motorhomes balance size and maneuverability but often experience sway, rear sag, and harsh ride quality when fully loaded. SuperSprings International’s bolt-on suspension systems address these challenges with progressive, maintenance-free support that improves stability, load distribution, and ride comfort—without air systems, compressors, or ongoing adjustments.

What Our Customers Are Saying

In our 2023 Winnebago View, we wanted the best ride possible. After 18 years with Class C motorhomes and no suspension upgrades, we installed blue front and black rear SumoSprings — and wow, what a difference. The RV feels more planted, with less sway in crosswinds and turns, yet no added stiffness or noise. Paired with rear Fox shocks, the ride is smoother, more stable, and far less tiring. It’s the closest our motorhome has ever felt to driving an SUV.

2023 Winnebago View

I installed SumoSprings on my Super C motorhome and was impressed right away. The installation was straightforward, and the difference on Colorado’s pothole-filled roads was huge — the sharp jolts are noticeably dampened, and the ride feels much smoother. Even the cabin is quieter while driving, which makes long days on the road far more enjoyable. I’m looking forward to our next extended trip to really put them to the test, but so far the improvement in comfort and control has exceeded my expectations.

Super C Motorhome

I completed a 500 mile trip in my sumospring equipped class c motorhome and I am very pleased with the performance! The tail wag is gone. I still feel the effects of passing trucks pushing air against the coach but it continues to track straight and recovers quickly. I let my brother drive the return trip and he described my motorhome as the best handling motorhome he has ever driven! Roadmaster anti-sway bars front and rear and SumoSprings front and rear together created and outstanding driving experience. Thanks again Super Springs !!
