How can I tell if my GM Truck has Autoride?

GM vehicles have a sticker called the Service Parts Identification Label located in the glove compartment (for trucks & SUVs) that includes information such as the vehicle’s VIN, Wheel Base, Model designation and a list of the vehicle’s 3 digit/character RPOs or Regular Production Options which are the options that car comes with. The code Z55 is the RPO code which indicates the option of Autoride electronic suspension.
