We list 32,383 parts from GM GENUINE, each with its manufacturer part number and verified vehicle fitment down to the exact year, model and engine. Browse the catalog below, or click any part to see its full application list.
If you're holding an old GM GENUINE part, match its number against the parts below — the fitment page for that number doubles as a cross-reference record. If you're starting from a vehicle instead, the vehicle catalog is usually faster: it filters to your engine first, then shows the GM GENUINE parts that fit.
How to Use GM GENUINE Part Numbers
A GM GENUINE part number is a precise identifier: it maps to one part and one set of vehicle applications, published by the manufacturer. That makes it more trustworthy than photos or descriptions, which change with packaging. When replacing a part, read the number off the old unit and match it here — the part's fitment page confirms whether it belongs on your year, model and engine.
If you need an alternative to a GM GENUINE part — or a GM GENUINE alternative to another brand — go through the vehicle: every part's fitment page links back to the vehicle catalog, where the same subcategory lists every brand with published fitment for that configuration. That's a live cross-reference, kept current with the application data.
