Does ACDelco only make GM parts?
No. ACDelco is General Motors' global parts brand that offers GM Genuine Parts for GM vehicles and an extensive aftermarket catalog that serves many other makes and models.
ACDelco’s catalog is organized into two primary streams: parts that are GM Original Equipment (GM OE) designed for GM vehicles, and the broader ACDelco aftermarket range that fits a wide variety of non-GM vehicles. This structure reflects GM's strategy to supply both factory-grade components for GM cars and a wide aftermarket lineup for independent repair shops and customers worldwide.
What ACDelco offers
ACDelco's portfolio splits into two broad lines to serve different buyers and markets. Here is a concise overview:
- GM Original Equipment (GM OE) parts: engineered and manufactured for GM vehicles; these are the components GM installs in its own factory production and they are sold through GM dealers and authorized distributors as GM Genuine Parts.
- ACDelco Aftermarket (Professional/Gold) parts: a large, cross-brand catalog of replacement parts intended for multiple makes and models; includes filters, brake components, electrical parts, batteries, and more; widely used by independent repair shops and retailers; many items fit non-GM vehicles when fitment is confirmed.
In practice, GM OE parts are GM-focused, while the ACDelco aftermarket range broadens the lineup to the wider automotive market. As of 2024-2025, GM continues to position ACDelco as a global, dual-purpose parts brand addressing both GM and non-GM customers.
GM Genuine Parts vs ACDelco Aftermarket
GM Genuine Parts are the official GM-branded components used in GM vehicles and sold through GM’s dealer network. ACDelco Aftermarket parts, while branded under ACDelco, cover a broad array of parts that may fit vehicles from many brands, depending on the part and the market. The distinction is primarily about branding and application scope rather than a hard-cut separation across markets.
Where to buy and how to identify parts
GM Genuine Parts or GM OE components are typically available through GM dealerships, official distributors, and some independent parts retailers who stock GM OEM lines. ACDelco Aftermarket parts are widely sold in independent auto parts stores and online retailers under the ACDelco name, with identification often showing the ACDelco brand and a fitment note. Always verify the part number and cross-check compatibility with your vehicle's make, model, and year.
Regional and branding notes
Regional branding can vary. In the United States, you may see GM Genuine Parts marketed distinctly from ACDelco, but both come from GM’s broader parts organization. In other regions, the labeling and packaging may differ, with the same components appearing under either GM OE or ACDelco branding. The important point for consumers is to verify fitment, part number, and warranty coverage rather than relying on branding alone.
Summary
ACDelco is General Motors’ global parts brand, but it does not produce only GM parts. Its portfolio includes GM Original Equipment parts for GM vehicles and a substantial aftermarket line that fits many makes and models. Consumers should check part numbers and vehicle fitment to ensure the right part is used, and consult a GM dealer if seeking GM Genuine Parts for a GM vehicle.
