ACDelco GM Original Equipment Air Lift Shock Absorbers are similar to standard shock absorbers, with the addition of an air chamber and rubber bladder built into the dust cover. These shock absorbers are GM-recommended replacements for your vehicle’s original components and have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. This air chamber and rubber bladder are inflated by an onboard air compressor to raise the vehicle during increased vehicle loads, assisting in the stabilization of alignment angles, improving handling, and reducing the risk of bottoming out.
