The GM Parts Hub
Genuine GM parts, decoded.
Chevrolet, GMC, Buick, and Cadillac. Dealer parts catalogs bury what actually fits under raw GM fitment codes and shorthand. GMPartPro translates that into plain English — every spec traced to a real source, backed by 17 years on a GM dealership parts counter.

Real parts-counter expertise
Sourced and structured by someone who spent 17 years in GM dealership parts operations — parts counter, wholesale ecommerce, and the GM EPC catalog system.
Fitment in plain English
Dealer listings often show raw GM shorthand like “without dual rear wheels, code PYQ.” We translate it into what actually fits — make, model, engine, and trim.
Sourced, or flagged — never guessed
Every fitment spec is traced to a real product listing and dated. When the source doesn’t state it, we mark it unverified instead of inventing a year range.
