Contitech Suspension Air Spring

Ride height and load support rely on air pressure, and the Contitech Suspension Air Spring provides the component that manages that function. The air spring expands with increased pressure and compresses as load changes, allowing the suspension to adjust dynamically. This behavior helps the vehicle respond to varying cargo weight without relying solely on mechanical springs. In real hauling conditions, stable ride height helps maintain balance across the axle. Since air pressure drives that adjustment, the Contitech 77303 keeps the suspension reacting to load changes.
