DEX Heavy Duty Parts specializes in renovated, recycled, and surplus parts for heavy- and medium-duty trucks in classes 6 through 8. The company operates two facilities, in Advance, North Carolina, and Oklahoma City, Oklahoma, with dedicated dismantling, testing, and renovation areas; the North Carolina site spans 38 acres and 210,000 square feet, while the Oklahoma site covers 25 acres and 153,000 square feet. Its catalog includes more than three million parts across over 30,000 categories, serving fleets, repair shops, owner-operators, and a nationwide dealer network with both OEM and all-makes aftermarket parts. In addition to engines, transmissions, and electrical components, DEX offers pre-painted and assembled body parts such as hoods, cabs, and bumpers. A notable development in 2025 was a partnership with Volvo Group North America, including the donation of a Volvo VNL 840 truck to the college's Diesel and Heavy Equipment Technology Program.
