ACDelco 530-500 Gold Professional Premium Gas-Charged Shock Absorber

The ACDelco 530-500 is part of the ACDelco Gold (Professional) Premium Gas-Charged Shock Absorber line — a high-quality aftermarket replacement designed to meet the fit, form, and function specifications of original equipment (OE) parts for General Motors vehicles as well as a wide range of other makes and models.

Key Features:

• Twin-tube passive design for reliable, consistent damping performance on passenger cars, vans, SUVs, and light trucks
• High-pressure nitrogen gas charge reduces fluid aeration for better response, less foaming, and more consistent control compared to non-gas-charged shocks
• Road Response Valving Technology automatically adjusts damping to deliver comfort under normal driving conditions and improved handling under demanding road conditions
• Hardened, chromed piston rod with micro-crack surface treatment provides an ultra-smooth, self-lubricating, corrosion- and scratch-resistant finish that extends seal life
• Drawn Over Mandrel (DOM) pressure cylinder ensures high-quality sealing properties and reduces internal friction for longer service life
• Full perimeter, multi-lip piston rod seal is permanently lubricated and helps prevent dirt and contaminants from entering the shock interior
• O-ring hydraulic piston seal minimizes piston blow-by for consistent, predictable control
• Infinitely variable damping delivers on-demand control across all road conditions
• Valve design independent of ride height reduces the negative effects of vehicle load changes or weakened spring conditions
• Backed by General Motors and subject to ACDelco's rigorous quality approval process

ACDelco Gold parts may have formerly appeared under the ACDelco Professional name. The 530-500 shock absorber is sold individually and is engineered to restore ride quality and handling stability to like-new performance.
