Most Class A Gas and Super C motorhomes are built on commercial truck platforms, engineered for durability and load capacity, not ride comfort. To compensate, RVers often add piecemeal upgrades: sway bars, track bars, Sumo Springs, Timbren, or air systems like Kelderman. But passive solutions target one behavior at a time, like roll, sway, or squat.
LiquidSpring is different. It’s a single, integrated system that monitors speed, steering, braking, and ride height 1000 times per second, and adjusts in 40 milliseconds – adapting instantly to the road. So long drives are easier, rough terrain smooths out, and crosswinds and passing semis are a breeze. LiquidSpring transforms your chassis into a completely different ride.
The RV brochure breaks down how LiquidSpring outperforms passive alternatives, with real test data showing up to 45% reduction in shock and vibration and up to 53% reduction in roll and sway. See full chassis compatibility across Class A Gas, Class C, and Super C platforms.
Commercial chassis are built for durability, not ride comfort. Expansion joints and uneven roads feel sharp and jarring, every mile a reminder of what's underneath you. LiquidSpring absorbs impacts in real time, continuously adjusting so no one notices the potholes. Just the view.
When crosswinds hit or a semi blows past, a lot can happen in a split second. Traditional upgrades like sway bars and track bars are fixed: never reacting to real-time or severity. LiquidSpring continuously adapts, keeping you stable and in control no matter what the road throws at you.
When you’re not fighting the road, long days feel shorter and drivers arrive fresher. LiquidSpring delivers ride quality that rivals a diesel pusher, without the cost of trading up. And when you reach your destination, Tru-Earth Leveling® handles the rest. No jacks, no blocks, no hassle. Just park, press, and you're level.
Whether you drive a Super C or a Class A Gas coach, learn how active suspension delivers comfort, control, and confidence without compromise
Our multi-link structure is directed by an onboard microprocessor that simultaneously monitors speed, steering, braking, and road inputs 1000x per second using a proprietary compressible fluid as the spring mechanism to provide the optimal ride and handling characteristics at all times.
LiquidSpring is engineered for the most popular Class A Gas, Class C, and Super C chassis on the road, including Ford F-53 (2010 and newer), Ford E350/450, Chevy/GMC G-3500/4500, Ford F-550/600, RAM 5500, International MV, and Chevy Silverado 5500 & 6500. If it's built on a commercial chassis, there's a good chance LiquidSpring fits.
Sway bars. Helper springs. Air bags. Each targets one behavior at a time, never the root cause. Even reactive air systems like Kelderman and Hendrickson need manual adjustments. No matter how many upgrades you stack, they lack real-time capability.
LiquidSpring replaces all of it with one fully active system that monitors driver and road inputs up to 1,000 times per second, adjusting in real time. That means consistent comfort and control, from merging to mountain passes.
Drive with confidence. Our CLASS® Product Limited Warranty delivers professional-grade protection, covering main structural components for 60 months or 100,000 miles, other components including power modules, electrical, and hydraulic for 36 months or 50,000 miles, and authorized labor for 12 months.
