ACDelco Advantage 520-396 Gas Charged Rear Shock Absorber

Key features

• 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
• Manufactured using quality materials and up-to-date equipment
