M&D Distributors

What M&D Distributors does

M&D Distributors is a US-headquartered distributor and remanufacturer of aftermarket diesel engine parts, serving heavy-duty trucking, infrastructure, agriculture, marine, and transportation end markets. Founded in 1943 as Magneto & Diesel Injector Service by the Ingram family and based in Humble, Texas, the company has accumulated more than 80 years of remanufacturing expertise and operates a catalog of over 150,000 parts across a network that has grown from 12 branches in 2021 to 33+ branches and 50 total locations spanning the United States, Mexico, and Canada, with stated coverage of 90% of the US population within a two-day shipping window.

The business is structured as a portfolio of subsidiaries and operating brands, including MemoParts, IDS Canada, Drexel Mexico, Drexel USA, Highway & Heavy Parts, DFI, SDg, TDG, TDE, DCW, and PRODIESEL, supported by formalized OEM partnerships with Bosch, Garrett, Cummins, Stanadyne, Holset, BorgWarner, Federal Mogul, and Diesel Cast Welding. Revenue is generated through sale and remanufacture of diesel engine components, combining parts distribution with in-house remanufacturing capability that the company highlights as a core technical competency.

Since September 2022, the company has operated under private-equity ownership via Gridiron Capital, marking a transition from a long period of family control to an institutionally backed growth phase. The acquisition of Diesel Testers in 2019 and the subsequent multi-subsidiary buildout indicate a roll-up-oriented strategy in a fragmented industrial aftermarket.
