GM Original Equipment
ACDelco GM Original Equipment Gas Charged Shock Absorbers control the oscillation of the suspension and are GM-recommended replacements for your vehicle's original components. A shock absorber is a hydraulic piston and cylinder that is designed to resist the up-and-down movement of the suspension. The shock has a valve or orifice that allows the piston to move up and down the cylinder tube at a controlled rate. The valving located at the bottom of the shock tube is tailored to the vehicle and suspension characteristics. These shocks feature a passive twin tube design and are nitrogen gas charged for consistent performance. These original equipment shock absorbers have been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
