What counts as Chevy OEM parts
Genuine GM Parts are produced by General Motors or under license to GM, and they are branded as Genuine GM Parts or GM OE.

- Distinct part numbers and packaging that help verify authenticity
In short, Genuine GM Parts are the official components produced or approved by GM for Chevrolets, and they are the recommended choice for repairs that require original specifications.
