What brand of parts does GMC use?
GMC relies on GM’s official parts brands for repairs and maintenance, primarily GMC Genuine Parts for OEM components and ACDelco for the broader GM aftermarket lineup.
How GMC sources its parts
GMC uses two primary branding channels for parts. The following outlines the main brands you’ll encounter and what they cover.
- GMC Genuine Parts — The official OEM parts line branded specifically for GMC vehicles. These parts are produced by GM or by suppliers contracted by GM and are designed to fit exactly with GMC models.
- ACDelco — GM’s global aftermarket parts brand, used for maintenance and replacement components across GM vehicles, including GMC models. ACDelco parts are widely available through dealers and retailers and are designed to meet GM specifications.
The practical takeaway is that most service and maintenance items come from these two sources, ensuring compatibility and warranty coverage when sourced through dealerships or authorized retailers.
GMC Genuine Parts vs ACDelco: What’s the difference?
GMC Genuine Parts
GMC Genuine Parts are the OEM components you’ll see listed as the correct parts for GMC vehicles. They carry the GMC branding and are backed by GM’s warranty and service networks. They may be produced by GM, or by partner manufacturers working under GM’s oversight.
ACDelco
ACDelco is the GM-branded aftermarket parts line. It covers routine maintenance and replacement parts such as brakes, filters, batteries, spark plugs, fluids, and more, designed to meet or exceed OEM specifications and widely distributed through GM channels and independent retailers.
The difference comes down to intended use: OEM-grade parts labeled “GMC Genuine Parts” are for exact factory specifications, while ACDelco parts serve the aftermarket replacement market with GM-approved standards.
Other sourcing and labeling considerations
Beyond the two primary brands, certain systems or regional operations may involve products from additional contracted manufacturers. In those cases, the packaging and part numbers will indicate the GM-approved spec, and you should verify compatibility using the vehicle’s VIN or GM part number.
- Parts can be manufactured by GM itself or by contracted suppliers under GM’s quality controls.
- Some components may come from third-party brands that GM has approved to meet GM specifications, especially for vehicles outside the U.S. or for specific modules.
- Always check the part number and labeling when ordering online or at a shop to ensure you’re getting the correct GMC Genuine Parts or ACDelco parts for your vehicle and year.
In practice, GMC owners are most likely to encounter GMC Genuine Parts at official dealers and ACDelco parts in aftermarket channels, with occasional third-party components that still meet GM specifications where authorized.
Summary
GMC’s part-brand strategy centers on two pillars: GMC Genuine Parts for OEM components and ACDelco for GM’s official aftermarket parts. Parts may come from GM or from contracted suppliers, depending on the component and market. For reliability and warranty, rely on GM-branded labels and verify part numbers with your dealer or the GM parts catalog.

Are GMC and Chevy parts the same?
Yes, many GMC and Chevy parts are the same because both brands are owned by General Motors and often use the same platforms, engines, and transmissions, especially for comparable models like the Silverado and Sierra. However, there are differences, with some body panels, trim features, and higher-end components varying between the two brands. Commodity parts like filters, bulbs, and basic electronics are also shared.
Shared parts
- Engine and drivetrain: GMC and Chevy models frequently share the same engine and transmission options.
- Chassis: They are built on the same platforms.
- Commodity parts: Standard items like tires, oil/air filters, spark plugs, and some electronic modules are often the same.
- Basic components: Internal components, such as power window motors, may be reused across different assemblies.
Different parts
- Exterior: Key visual components like the grille, headlights, and bumpers often differ between GMC and Chevrolet models.
- Trim and features: GMC trucks are typically positioned as more premium and may include higher-end standard features and materials, such as different interior trim or standard bed lighting that is optional on the Chevy.
- Upgraded components: In some cases, GMC vehicles may have slightly stronger or more robust versions of certain parts, like braking systems, suspension, or wheel axles, in comparison to their Chevy counterparts.
How to confirm part compatibility
- Check vehicle-specific compatibility: Use your specific year, make, and model to find the correct parts, as some variations exist even between shared components.
- Consult parts databases: Websites for auto parts stores or official GM sites will list compatible parts based on your vehicle's information.
