Review on Enhance your vehicle's performance with ACDelco GM Original Equipment Rear Air Lift Shock Absorber 580-1093 by Joseph Elvis

They fit perfectly on my 2009 GMC Yukon Denali AWD with Z55 rear suspension. The dealer asked for $1,300 for a replacement, including labor. Did some research and finally found them. My normal shock absorbers broke, causing the compressor to work a lot. The airbag's rubber cover also appears to be made of more durable rubber. Installation took less than 30 minutes, which made it easy to remove the wheels. Check the label on your glove box and it will tell you which one you have. The Z95 is another mag ride shock. Lifespan is currently unknown.
