What is an air spring bag strut? Sometimes it is called an air spring, air shock, air bag or bellows. a conventional strut uses a steel coil spring but an air strut employs an air spring bag or bellow. This makes the ride more comfortable and gives the driver more control of ride height.

The most common reason for an air strut failure is due to dry rotting of the air spring bag. This is something that happens over time, the rubber starts to deteriorate and causes leaks, when this happens the air bag can no longer hold air pressure. A leaking air bag can cause the strut it fits over to fail as well. The second factor of an air strut failure is the strut itself. The strut is pressurized with fluid, and if the strut begins to fail it will no longer have the same pressure to hold the vehicle. If this system begins to fail one visible sign will be that your vehicle will be lower than factory height.

If air struts are not replaced on time it will cause air suspension compressor failure.
