Introduction Air suspension is a type of vehicle suspension powered by an electric or engine-driven air pump or compressor. This compressor pumps the air into a flexible bellows, usually made from textile-reinforced rubber. An air spring system provides a cushion between the vehicle body & wheel to reduce the vibration felt during travel. Maxpeedingrods provides performance aftermarket Air suspension compatible for Chevy & compatible for GMC series. You can enjoy a comfortable riding experience in all road conditions.
