Original GMC OEM parts catalog. Pick a series and generation to open factory diagrams and genuine part numbers.
Series
This GMC parts catalog is a GM EPC-style original parts catalog. It organizes GMC by series and generation the way the General Motors electronic parts catalog does, then hands off to the matching OEM diagrams. Use it as a GMC OEM catalog when you need factory structure rather than a mixed aftermarket list.
In search terms this page is a GMC parts catalog and a GMC OEM catalog: series, generations, and diagrams on one host. GMC sits in the General Motors catalog family, known in workshops as GM EPC. Original part numbers are not listed in this text; they appear on the exploded diagrams after you choose a generation.
Pick a GMC series, open the generation for the right years, then continue to the 7zap GMC catalog. GM EPC-style exploded views and VIN-accurate lookup are attached to that generation, not to a free-text model search. If a series has several generations, use the year range on each card — facelifts are separate when the GMC catalog has them, because diagrams often change there.
Across the full GMC OEM catalog this host lists 21 series and 243 generations. Notable and long-running lines in this data include Sierra (1989–2021), Yukon (1992–2021), Savana (1999–2021), Acadia (2007–2025), Canyon (2004–2025), C/K Series (1973–2001), Jimmy (1983–2001), Sonoma (1991–2005), Suburban (1985–1999), and Envoy (2002–2009). Those names are taken from the series in the brand payload, not from the filtered grid above. Year ranges are the span of generations in the catalog, not a marketing timeline.
GM EPC data is held together by original part numbers, supersessions, and assembly diagrams. That is the difference between this GMC parts catalog and a generic aftermarket listing that only claims a year-and-model fit. Here you can see how a part sits on the factory layout before you order.
Regions matter in an OEM catalog because the same GMC series can carry different generations, year spans, and diagrams by market. On this subdomain the regions in the data are Canada, Europe, Middle East, USA, Africa, and Asia. The region switcher only changes which series appear in the grid; this article describes the whole GMC catalog, not a single market. The catalog covers cars, commercial vehicles, trucks, and special vehicles. Those types share this GMC host; the type switcher only changes which series appear in the grid, not the page or this article.
Open a generation to continue in the 7zap GMC catalog for exploded views and VIN-accurate lookup. That step stays on the GMC OEM path: the same series and generation, with factory diagrams.
