It installs between the axle assembly and the vehicle frame where compressed air fills the spring chamber to hold the chassis above the axle. As cargo loads shift during operation, air pressure inside the chamber changes, and the suspension height rises or lowers accordingly. This movement allows the suspension to react to bumps and load variation during travel. Because air ride assemblies rely on air springs to manage vehicle load and movement, the Firestone W013589306 is used as a replacement suspension air spring kit in compatible systems.
