Option code Z71 · Performance
Off-Road Package
The most famous RPO of all: off-road suspension, hill-descent, skid plates and all-terrain tires — and a badge that gets faked, which is why buyers verify it on the SPID label.

How to confirm it on a real car
GM RPO records factory equipment on the Service Parts Identification (SPID) label in the glovebox. Stickers go missing and cars get modified, so the ground truth for any specific VIN is the factory build record: every option code the car was born with, including Z71 if it was ordered.
Was Z71 on your car's original build?
The CarWhere build sheet decodes any GM VIN into its full factory record — every option code, the original paint, trim and equipment, as built. $9.99, instant.
