2012 Yukon XL Autoride or not

I looked at purchasing the Eibach Pro-Plus Lowering kit and while configuring the order there’s an option for Autoride and w/o Autoride. How do I tell if I have it or not? Certain code in the VIN?

RPO sticker in glove box will have all your option codes. Look for Z55

It appears I have it. Since I bought the truck with 140K, I've never heard the compressor kick on. Time for some troubleshooting but more than likely I will replace all shocks, struts, and compressor.
