ACDelco Gold 530-387 (19158785) Premium Gas Charged Rear Shock Absorber

ACDelco Professional Premium Gas Charged Shocks are twin-tube passive replacement shocks for passenger cars, vans, SUVs, and light trucks. These shocks have a high pressure nitrogen gas charge along with chrome finished piston rods and drawn over mandrel (DOM) pressure cylinders. For additional ride support, ACDelco Professional Premium Gas Charged Shocks utilize premium Road Response Valving Technology that automatically adjusts to provide comfort and extra control by responding to changing road conditions during normal driving situations, and improved handling under extreme road conditions.

• A hardened, chromed piston rod with micro cracks provides an ultra-smooth, self-lubricating, corrosion- and scratch-resistant surface, helping increase seal life
• Drawn over mandrel (DOM) pressure cylinder for high quality sealing properties and reduced internal friction to assist with longer product life
• Gas charged for reduced fluid aeration, which can result in better response, less foaming, and more consistent control than non-gas charged shocks
• Full perimeter, multi-lip, piston rod seal is permanently lubricated and helps keep dirt and contaminates from reaching the interior of the rod
• O-ring hydraulic piston seal resulting in minimized piston blow-by and consistent control. Stroke Length-8.69 inch. Dust Shield
