ACDelco Professional 530-189 Premium Gas Charged Rear Shock Absorber
- 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.
