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
- 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
- O-ring hydraulic piston seal resulting in minimized piston blow-by and consistent control
- Valve design performance that is independent of ride height reduces the potentially negative effects of vehicle loads or weak spring conditions

|FAQ - A1||Yes, though shocks and struts perform a similar function, they vary greatly in their design. Struts are an integral part of a vehicle's suspension system, providing structural support for the vehicle and, as such, are a safety subsystem. Shocks work separately from any structural function, simply absorbing and damping the bumps from the road.|
|FAQ - A2||Yes, all shocks and struts use hydraulic fluid (oil) to control damping. A gas charged shock or strut uses high-pressure nitrogen gas to reduce oil foaming during high-speed damping, and therefore maintains performance.|
|FAQ - A3||Yes, it is possible to do a quick check at home for wear on your vehicle's shocks or struts. You can look for any physical damage to the shock or strut housing or any leaking - this is especially common on rear units that tend to have stones kicked up by the front wheels. You can also perform a bounce test by taking each corner of the vehicle and pushing down hard. The corner should drop, rise and settle again. If the body continues to move up and down, there's a good chance your shocks need to be replaced. Though these home tests can indicate worn shocks or struts, it is also recommended that you take your vehicle to a qualified service technician and let them do a thorough inspection every 12 months or 12,000 miles.|
|FAQ - A4||Yes, if you are replacing your vehicle's struts. However, it is not necessary to get your vehicle aligned when replacing your vehicle's shocks unless there was or is a previous issue.|
|FAQ - A5||Yes, it is important to choose the correct shock or strut for your vehicle model and year, as well as for the location in the vehicle.|
