Browse our inventory of used OEM GMC parts sourced from US-based salvage facilities. Every component is a genuine factory-original part inspected for condition and listed with full vehicle compatibility details. GMC shares every platform with Chevrolet — the Sierra is the Silverado, the Yukon is the Tahoe, the Acadia is the Traverse — which means the much larger Chevrolet donor pool is fully accessible to GMC owners. Free shipping on all US orders. VIN fitment confirmed before dispatch.
GMC and Chevrolet have shared their entire platform lineup under General Motors since the modern era. There is no structural, drivetrain, or engine component unique to GMC that does not also exist on an equivalent Chevrolet, Buick, Cadillac, or Saturn platform vehicle. This is the single most important piece of knowledge for any GMC owner sourcing used parts — the combined GM family donor pool is one of the largest in the industry, providing outstanding availability across transfer cases, differentials, subframes, ABS systems, and intake manifolds.

What We Stock — by Part Category
Carrier, Differential & Transfer Cases (14 units)
The largest part category in our GMC collection — covering transfer cases and differential carriers for Sierra, Yukon, Acadia, Terrain, and Envoy. All units are mileage-verified and fluid-inspected before listing. Every carrier, differential, and transfer case carries a 90-day warranty from confirmed delivery. Always confirm gear ratio, AWD/4WD variant, and transmission type before ordering any differential or transfer case component.
ABS Pump Assemblies (7 units)
ABS pump and modulator assemblies for GMC's truck, SUV, and crossover lineup. Always pull OBD-II fault codes before ordering — wheel speed sensor codes (C1234–C1237) frequently cause ABS warning lights without pump failure. Confirm your production year and 2WD/4WD configuration, as these determine the correct ABS assembly variant.
Intake Manifolds (3 units)
Upper intake manifold assemblies for GMC V6 and V8 applications. GM's Vortec and EcoTec3 engine families are shared across Sierra, Yukon, Envoy, Canyon, and equivalent Chevrolet platforms — confirm your engine code and displacement before ordering.
Radio & Navigation Units (4 units)
Factory radio, navigation, and infotainment receivers for GMC trucks and SUVs. GM infotainment units often require VIN programming after installation on vehicles with OnStar integration — confirm your trim and infotainment package before ordering.
Subframes & Engine Cradles (4 units)
Front subframe and engine cradle crossmembers for GMC crossovers. GMC Terrain and Acadia subframes cross-reference with Chevrolet Equinox and Traverse respectively — expanded donor availability at consistent pricing.
🔧 GMC = Chevrolet for Parts Purposes
If the specific GMC part you need isn't listed, search for the Chevrolet equivalent — Sierra owners search Silverado, Yukon owners search Tahoe or Suburban, Acadia owners search Traverse, Terrain owners search Equinox, Envoy owners search TrailBlazer.
