GM Genuine Parts Automatic Transmission Differential Pinion Gears are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These gears are a component of the differential gearbox. All of the different parts in the gearbox, such as pinion bearings, rings, and gears, work with your vehicle's transmission to deliver power from your engine to the axels that turn your wheels so that they can spin independently but are still linked together. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
