About GMC Sierra parts
GMC Sierra parts are available for every generation since 1999, including the 2007–2013, 2014–2018 and 2019 and newer trucks and the heavy-duty 2500 and 3500. Popular pulls include 5.3L and 6.2L V8 and Duramax diesel engines, transmissions, transfer cases, axles, doors, tailgates and seats.
The Sierra shares its engine, drivetrain, doors, bed and most interior parts with the Chevrolet Silverado of the same generation. The grille, hood, headlights and front fenders are GMC-specific. Use the RPO codes in the glove box to match options.
