It uses a rolling lobe / reversible sleeve design to support the vehicle's load and cushion road shocks, replacing worn or leaking original air springs. Typical replacement is needed when the rubber bellows crack, leak air, or no longer maintain proper ride height. This air spring is a direct fit for many Holland (Neway) and Binkley suspension systems.
