ACDelco Specialty 504-508 Rear Air Lift Shock Absorber


Product description

ACDelco Specialty Air Lift Shocks are designed to help provide better handling for temporary situations, such as when a vehicle hauls a heavy load or tows a trailer. They have an adjustable air pressure, between 25 and 200 psi, and up to 1,100 lbs (per pair) of load-carrying capacity*. Under loaded conditions, these shocks help maintain level vehicle height by adding or releasing air as needed, assisting in the stabilization of alignment angles, reducing other suspension component wear, improving handling, and reducing the risk of bottoming out. ACDelco Specialty Air Lift Shocks are ideal for temporary load hauling, including towing boats and trailers. *Not to exceed vehicle GVWR (Gross Vehicle Weight Rating). Product does not increase payload.

Maintenance Tips

Your vehicle’s struts slowly deteriorate over time, though this wear is normally difficult to detect. Worn struts can also cause additional wear to other vehicle components. To maximize your vehicle’s ride comfort, it’s recommended to inspect your vehicle’s struts every year. Be sure to always refer to your vehicle Owner’s Manual for additional vehicle maintenance practices. Potential affected components may include ball joints and other suspension components, brakes, and tires. The following should be checked by a qualified technician:

  • Leaking oil or wetness along the body of the shock or strut
  • Broken mounts
  • Broken, damaged, or missing mounting hardware
  • Dented reservoir tube
  • Bent or scratched piston rod
  • Cupped tire wear
  • Damaged spring seat, spring


  • Is there a difference between a shock and a strut? Yes. While shocks and struts perform a similar function, they vary greatly in their design. The major difference between shocks and struts is that a strut is a structural part of the vehicle’s suspension system, while a shock is not. A strut is also a crucial part of the vehicle’s steering system and greatly affects alignment angles. S
  • hould I have my vehicle aligned after replacing my shocks or struts? You should have your vehicle aligned if you are replacing your vehicle’s struts. However, it’s not necessary to get your vehicle aligned when replacing your vehicle’s shocks unless there was a previous issue. D
  • o I need different shocks or struts for front, rear, left, or right applications? Yes. It’s important to choose the correct shock or strut for your vehicle model and year, as well as for the location in the vehicle.

Our Reviews

I have memories of a lifetime now. Your very informative website helped me every step of the way. To say the website is a God-send is a vast understatement, I literally booked every single hotel room, activity and excursion through the website. Michael Dunphy
The trip was awesome, thanks to the tips we got from you and your website! We were confused by the various glacier options and Denali National Park. Your website as well as quick yet detailed responses from you made us plan our trip well. Srinivasan Krishnan
I used this app for driving from Seward to Anchorage and then to Denali. A gold mine of info! It told me things to see and do and had interesting stories about the places along the way. Explorer2019
