Class C Motorhome

Class C motorhomes strike a balance between space and drivability, but they’re still prone to sway, rear sag, and rough rides under load. Our bolt-on suspension upgrades reduce sway, improve load distribution, and absorb road shock — all without air systems, compressors, or constant maintenance.

Strength Without Sacrificing Comfort

Best Class C Upgrades

Class C RVs often carry heavy passenger loads, fresh water, and gear, which can push the limits of stock suspension. SumoSprings Rebel and Maxim kits provide progressive support that adjusts automatically to your load, reducing sway and keeping your RV stable whether you’re on the interstate, maneuvering through small towns, or camping off-grid.

✅ SumoSprings Rebel – Two-piece design for articulation and consistent load support.
✅ SumoSprings Maxim – Large-diameter progressive springs for maximum stability and weight handling.

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 !!
