ACDelco 530-311 Shock Absorber

Description:

Features and Benefits:

• 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
• Full perimeter, multi-lip, piston rod seal is permanently lubricated and helps keep dirt and contaminates from reaching the interior of the rod
• Gas charged for reduced fluid aeration, which can result in better response, less foaming, and more consistent control than non-gas charged shocks
• Infinitely variable damping for on-demand control on all road conditions
• Manufactured to meet specifications for fit, form, and function for General Motors vehicles as well as most makes and models
• O-ring hydraulic piston seal resulting in minimized piston blow-by and consistent control
• Premium aftermarket replacement part
• Some ACDelco Gold parts may have formerly appeared as ACDelco Professional
• Valve design performance that is independent of ride height reduces the potentially negative effects of vehicle loads or weak spring conditions

• To inspect your shocks and struts to gauge wear, check for:
• Your vehicle's shocks and struts slowly deteriorate over time, though this wear is normally difficult to detect. To maximize your vehicle's ride comfort and safety, it is recommended to replace your vehicle's shocks and struts every 50,000 miles. Worn shocks and struts can also cause additional wear to other vehicle components. Affected components include:
