Hi my name is fred and I have a 2000 yukon SLT Ilooked in glove box to see RPO codes and mine says Z55 and there are air shocks on the rear with both connectors on but they are shot. I want to replace them and the compressor but theres no compressor to be found can someone help please.

 

Hi Fred. My name is Mike. I just replaced shocks and compressor on my 2005 Tahoe. I got the parts from Suncore Industries in Florida. My compressor was on the outside of the frame rail on the driver side. Couldn't miss mine. Not sure if yours would be same place. Only 3 bolts holding it on. Sun ore had remanufacture shocks a lot cheaper then the dealer. They have been working fine for me. If I can be anymore help email me at mmorton9@yahoo.com. Good luck
