It replaces the Firestone W01‑358‑7555 and other OEM numbers from Goodyear, Contitech, and many aftermarket suppliers. The air spring supports the vehicle’s load, absorbs road shocks, and maintains consistent ride height. Replace it when the rubber bellows show cracking, air leaks, or the internal bumper deteriorates.
