Seidel Diesel Group

What Seidel Diesel Group does

Seidel Diesel Group (SDG), founded in 1981 and headquartered in Bolingbrook, Illinois, is a US-based specialty distributor and remanufacturer of diesel fuel system components and turbochargers. The company's core product portfolio covers diesel fuel injection pumps (VP44, VP30, CP3, CP4, DS, CAPS, and TDI), fuel injectors (common rail, traditional, and Delphi lines), and turbochargers from Garrett, Holset, BorgWarner, and the proprietary SDG VGT line, complemented by accessories such as fuel contamination kits, diesel additives (Alliant Power, Stanadyne, Power Service), Proheat cabin and coolant heaters, and Steinbauer performance modules. SDG also operates in-house test bench services for injector and pump diagnostics and is Bosch 4-Star Certified and ISO-certified at its Bolingbrook facility.

The company serves three primary customer segments: diesel pickup truck owners (Ford Power Stroke, Chevy/GMC Duramax, Dodge/Ram Cummins) as the dominant vertical, agricultural operations requiring diesel parts and performance upgrades, and commercial fleet operators. Its go-to-market is direct-to-consumer and direct-to-SMB via its e-commerce website and 11 physical branch locations spread across Illinois, Oregon, Connecticut, North Carolina, Florida, Pennsylvania, and Massachusetts, supported by technical content (application guides, troubleshooting tools, Diesel On Demand videos) and SEO-driven organic search.

Revenue is generated through one-time parts sales, professional testing services, and hardware/accessory sales under a quote-based pricing model with no published list pricing. Authorized distributor relationships with Bosch, Garrett, BorgWarner, Holset, and Delphi underpin the product offering. SDG was acquired by M&D (M&D Distributors) in July 2023 and continues to operate under its existing brand and branch footprint post-acquisition. The company employs 51-100 people and has been recognized with the 2022 BorgWarner Bronze Sales Award via its Turbo Exchange division.
