ACDelco Gold 504-550 (88946638) Rear Air Lift Shock Absorber

ACDelco Specialty Air Lift Shocks are designed to help provide better handling for temporary situations, such as when a vehicle hauls a heavy load or tows a trailer. They have an adjustable air pressure, between 25 and 200 psi, and up to 1,100 lbs (per pair) of load-carrying capacity. Under loaded conditions, these shocks help maintain level vehicle height by adding or releasing air as needed, assisting in the stabilization of alignment angles, reducing other suspension component wear, improving handling, and reducing the risk of bottoming out. ACDelco Specialty Air Lift Shocks are ideal for temporary load hauling, including towing boats and trailers. Not to exceed vehicle GVWR (Gross Vehicle Weight Rating).
