LiquidSpring LLC manufactures CLASS® suspension systems for ambulances, shuttle buses, RVs, and military vehicles. CLASS®, or Compressible Liquid Adaptive Suspension System, is the next generation of vehicle suspension systems, taking a "smart" approach. Its sophisticated on-board microprocessor and eight (8) degree-of-freedom vehicle model adapts the entire vehicle's response to road variations and the driver. Unlike current steel and air spring suspension systems, CLASS® is the only suspension system that can automatically and instantaneously change the spring stiffness and damping at each wheel over a very broad range with minimal power consumption while the vehicle is being driven. In other words, you get a smoother ride, safer handling, and lower maintenance costs. CLASS® - Smoother, Safer, Smarter.
