SPECIFICATIONS Position Rear WARNING CA Proposition 65 No   Suncore Industries was established in 2000 and have been a member of the Automotive Parts Rebuilders Association (APRA) ever since. Our mission began with rebuilding air suspension components and moved quickly into offering better solutions with conventional suspension conversion kits to give our customers the longevity they can rely on. The most common reason for an air strut failure is due to dry rotting of the air bag. This is something that happens over time, the air bag 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 an Air Suspension Compressor Failure.
