An air suspension spring is comparable in function to a coil spring on a conventional suspension system; however, the air spring bladder is flexible and has a specific amount of elasticity making it an ideal design for a variable system. Road debris, extreme temperatures, environmental conditions and excessive loads can cause the air suspension spring to fail over time.
