Product: ACDelco Advantage 520-396 Gas Charged Rear Shock Absorber
Brand: ACDelco
Super-finished chromed piston rod inhibits corrosion and provides a more consistent wear surface
Piston seal adjusts as it wears to maintain a tight seal between the piston and pressure tube. This minimizes leak paths for a longer, more consistent, product life.
O-ring provides constant pressure to the inner tube and makes the valve less susceptible to dirt, wear, and fatigue leading to longer service life
Drawn over mandrel (DOM) pressure cylinder for a smoother surface and less resistance, resulting in increased service life
