GM Parts

Cottonwood Surplus Sales stocks hundreds of genuine GM parts, including OEM components for Chevrolet, GMC, Cadillac, and Buick vehicles — from Silverado pickups to Camaro sports cars. Sourced from dealerships nationwide, our inventory covers nearly every system on the vehicle: brake pads and calipers, oxygen sensors, oil pressure switches, wiring harnesses, transmission filters and gaskets, CV axle shafts, mirrors, seat belts and buckles, cargo mats, emblems, and interior trim.

Every listing includes the exact GM part number, so you can match your vehicle's original equipment with confidence instead of guessing at aftermarket fitment, giving you OEM reliability without dealer pricing.

Search by part number if you know exactly what you need, or contact us for help with fitment. New parts are added regularly as fresh surplus comes in.
