SumoSprings use a high-tech closed-cell foam — not air — to do the heavy lifting.
Each SumoSpring is made from millions of microscopic air pockets trapped in microcellular polyurethane. As loads change, these air cells compress and rebound to deliver smooth, consistent damping — without relying on airlines, valves, or compressors. That means no leaks, no adjustments, and no downtime — just plug-and-play performance.
One‑piece spring for light‑to‑moderate loads. Installs in the factory bump‑stop location with minimal changes.
Oversized springs built for maximum load support—ideal for Class A/B/C motorhomes and heavy-duty work trucks. Available in Blue, Black, and Yellow densities to match your vehicle’s load class.
Two‑piece spring system offering full suspension articulation; ideal for lifted service trucks, off‑road builds or unique upfits.
Three spring densities. Three designs. One clear upgrade from air and steel.
1. Identify the vehicle’s base suspension (coil or leaf), payload range and operating scenario.
2. Select the density (Blue, Black, Yellow) that matches your load profile.
3. Choose the style (Solo, Rebel, Maxim) based on chassis, articulation, lift or build‑out.
4. Install and drive — no airlines, no adjustments, no maintenance.
5. Keep your fleet moving with fewer interruptions, more consistency and better stability.
Each SumoSpring is available in multiple densities — Blue for lighter loads, Black for balanced support, and Yellow for maximum capacity. Whether you drive a van, truck, RV, or trailer, there’s a spring that fits your chassis and matches your weight class. And with three mounting styles (Solo, Rebel, Maxim), it’s easy to pick the right setup — all without compressors, metal fatigue, or guesswork.
