Your vehicle suspension is a system of components that connect the frame to the wheels, thereby isolating it from the road and allowing relative movement. In addition to supporting the full weight of the vehicle, the suspension system also affects the attitude, driving height, handling and driving quality.
Air suspension is a kind of automobile suspension which uses air spring instead of traditional steel spring. Air springs, suspension sensors and computer operated vents on the on-board air compressor enable the system to maintain ride height and change the ride characteristics of the suspension.
