ACDelco Silver 520-432 (19295556) Conventional Gas Charged Rear Shock Absorber

ACDelco Advantage Gas Charged Shocks are the economical, twin-tube option for your passenger car, van, SUV, or light duty truck. These gas charged shocks include super-finished chromed piston rods, oil seal with integrated dirt wiper, durable piston valve assembly, and a drawn over mandrel (DOM) pressure cylinder. ACDelco Advantage Gas Charged Shocks are tested to ensure vehicle fit and quality ride.

• 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
