It is a direct replacement for the Firestone W01-358-9781 and Goodyear 1R12-603 air springs, commonly found on Freightliner Cascadia, Century, Coronado, and Columbia models. The air spring supports the vehicle's weight, provides a smooth ride, and maintains proper ride height. Replace it when the air bag leaks, cracks, or fails to hold pressure, causing the vehicle to sag or ride roughly.
