## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great air shocks at a great price.
*by P***Y on August 4, 2019*

Was looking for shocks for 94 K1500, saw these in the 50 buck range, ordered. Seem like good quality air shocks, installed them in an evening. Hose kit for filling was included. Replacement bolts were not, had to reuse old ones, luckily they were not frozen from the rust. I used them towing a dual axle trailer with over a ton of scrap metal in it. Seemed to work well. Made in Mexico.

### ⭐⭐⭐⭐⭐ Works great
*by S***W on November 6, 2023*

These are easy to install and they work great. Put these on my sons 1998 Chevy 1500. Definitely worth the money.

### ⭐⭐⭐⭐ ... one ton Chevy as much as i would have liked, but with 300k on the suspension
*by T***R on September 19, 2015*

Didn't life the old one ton Chevy as much as i would have liked, but with 300k on the suspension, you cant expect miracles. Went on exactly as you would expect. Plenty of hose. I ended up running the valve in the both hole of my licence plate, odd place but it was a perfect fit. They say they hold 200 psi, my compressor only goes up to about 120. At that pressure, i really don't think the shocks have made the ride any rougher. Solid buy, will buy again if i get in the mood for air shocks again.
