ACDelco Advantage 520-42 Gas Charged Front Shock Absorber

The ACDelco Advantage 520-42 Gas Charged Front Shock Absorber is designed for passenger cars, vans, SUVs, and light-duty trucks. This economical twin-tube shock absorber features super-finished chromed piston rods that inhibit corrosion and provide a consistent wear surface. The piston seal adjusts as it wears, maintaining a tight seal to minimize leaks and extend product life. An O-ring ensures constant pressure to the inner tube, enhancing durability against dirt and wear. With a drawn over mandrel (DOM) pressure cylinder, it offers a smoother surface and reduced resistance, resulting in increased service life. • 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, minimizing leak paths • O-ring provides constant pressure to the inner tube, enhancing durability • Drawn over mandrel (DOM) pressure cylinder for smoother surface and less resistance
