It replaces the air spring component that supports the vehicle's weight and absorbs road shock by using compressed air inside a flexible rubber bellows. You typically replace it when the original air bag develops leaks, cracks, or fails to hold air, causing the suspension to sag or ride roughly. Known technically as the Firestone 1T15M-.5 bellows, it's a common service part for maintaining proper ride height and load leveling on commercial vehicles.
