About this item

  • Super-finished chromed piston rod inhibits corrosion and provides a more consistent wear surface
  • Piston seal adjusts as it wears to maintain a tight seal between the piston and pressure tube. This minimizes leak paths for a longer, more consistent, product life.
  • O-ring provides constant pressure to the inner tube and makes the valve less susceptible to dirt, wear, and fatigue leading to longer service life
  • Drawn over mandrel (DOM) pressure cylinder for a smoother surface and less resistance, resulting in increased service life
  • Manufactured using quality materials and up-to-date equipment


ACDelco Advantage Gas Charged Shocks are the economical, twin-tube option for your passenger car, van, SUV, or light duty truck. These gas charged shocks include super-finished chromed piston rods, oil seal with integrated dirt wiper, durable piston valve assembly, and a drawn over mandrel (DOM) pressure cylinder. ACDelco Advantage Gas Charged Shocks are tested to ensure vehicle fit and quality ride.

I was surprised that I could get Ac Delco shocks for my tahoe for such a great price. They arrived quickly and were packaged well. My original shocks were oil filled and completely worn out. These fit perfectly and ride nice and firm. I wish I would have bought Ac Delco for the front as well. Hopefully they last a long time.

Wow couldn't believe the price and easy install. My girlfriend said her 2003 chevy tahoe rode so nice and made such a difference. I could feel the difference as a passenger! I hope they last a few years. Thank you!

Worked great on a 2007 Escalade ESV. Easy to install and much cheaper than going to the dealer for shocks.

For the money, I was incredibly impressed. These are the correct fit, and replace the factory non gas charged shock directly. The ride is slightly firmer because of the gas charge, but they ride quite well and enhance handling characteristics especially when loaded. Comfortable firm but not harsh ride. Best part of all is they lasted well beyond what I guessed they would. For @ $53 a pair, I am perfectly content with the 50K plus miles they provided. I am purchasing another set today.

They are NOT OEM replacement. They are economy grade shocks with an ACDelco sticker added to them. Not stamped/engraved like to OEM shocks.

AC Delco factory replacement parts. What else can you say? Lol. You get what you pay for and these were a good deal and seem to be good quality.

Perfect fit. Exceeds OEM expectations for my 2013 Chevrolet Suburban LTZ 1500 4X4. Instant change in road handling. Again better than OEM.
