It replaces the original Firestone W01-358-7555 and fits Reyco 20018-01 and Binkley XB-SPN-053-37 air ride systems. The air spring supports the vehicle's weight and cushions the ride by adjusting air pressure. It should be replaced when the rubber bladder cracks, leaks, or fails, which causes the suspension to sag or ride harshly.
