Air suspension is a type of vehicle suspension powered by an engine driven or electric air pump or compressor. This pump pressurizes the air, using compressed air as a spring. Air suspension replaces conventional steel springs. If the engine is left off for an extended period, the vehicle will settle to the ground. The purpose of air suspension is to provide a smooth ride quality and in some cases self-leveling.
