RPOs are three-character alphanumeric codes that define every option on a GM vehicle (e.g., G80 for rear locking differential, Z71 for off-road suspension). The Global EPC allows you to search by RPO alone, which is vital when the VIN is unavailable (e.g., a crate engine or a transmission on a pallet).
