Ordering the wrong brake caliper for a 2018 Chevrolet Silverado or misidentifying a transmission mount for a 2010 Buick Enclave can lead to costly downtime and frustrated customers.

General Motors uses Regular Production Option (RPO) codes to define vehicle build specs (e.g., "Z71" for off-road suspension). The Global EPC allows users to search by these codes, ensuring that parts like shocks or springs match the factory suspension package.
The catalog is not just text; it features interactive exploded-view diagrams. These technical illustrations show how components fit together, making it easier to identify a part's location and adjacent fasteners. Mechanics can click on a number in the diagram, and the system highlights the corresponding part number and price.
