What D&W Diesel makes

D&W Diesel is a national distributor and remanufacturer of diesel engine components and industrial products for mobile and industrial equipment. The company started in 1976 as a rebuilder of starters and alternators in a rented one-bay garage in Auburn, New York, and now runs a 110,000 square foot headquarters that warehouses and remanufactures engine components, hydraulic components and PTOs, tank truck equipment, industrial products, and hoses. Its online catalog carries more than 1.5 million cross references across diesel engine parts, hydraulics, PTOs, hose, and industrial air compressors.

Remanufacturing is a core line, not a sideline. D&W rebuilds rotating electric (starters and alternators), fuel injection components, turbochargers, and hydraulic components including pumps, motors, valves, and hydrostatic transmissions. On the distribution side it stocks parts from turbocharger and rotating-electric brands including BorgWarner, Garrett Advancing Motion (D&W is a master distributor), Hitachi, IHI, and Mitsubishi, plus Gardner Denver industrial air compressor systems. A separate engineering group designs, builds, and installs custom tank truck systems for loading and unloading liquid and dry-bulk materials, and the hose shop assembles custom hydraulic, chemical, and food-grade lines from stocked ends, couplings, adapters, and clamps.

The service side is built to keep equipment running. D&W offers drive-in service at several branches, diesel oxidation catalyst and diesel particulate filter (DOC and DPF) cleaning, component testing, field service, and 24/7 on-site maintenance for compressed air systems. That mix of distribution, in-house remanufacturing, and field service is what positions the company against pure parts resellers.

Ownership and history

Founded in 1976, D&W Diesel is 50 years old in 2026 and has grown from that single garage bay into a business with over 350 associate owners and eight branch locations beyond its Auburn headquarters. The branches sit in Latham, Buffalo, and (per 2021 coverage) Rochester, New York; North Oxford, Massachusetts; Cliffwood and Sewell, New Jersey; Maple Heights, Ohio; and Denver, Colorado, giving the company coverage across the Northeast and a western outpost.

In the fall of 2021, founders Dave and Doug sold D&W to Jasper Holdings, Inc., an Indiana-based employee-owned holding company, in a transaction on which KPMG Corporate Finance advised. D&W continues to operate independently under its own brand, and Greg Wrona, a 13-year D&W associate who had been Vice President, was named President. Through Jasper Holdings the company is employee-owned: its associates participate in the group's Employee Stock Ownership Plan (ESOP), which is why D&W describes itself as employee owned since 2021 and its associates as associate owners. In 2025 Jasper Holdings ranked 23rd on the National Center for Employee Ownership (NCEO) Employee Ownership 100 list.

Certifications and quality

D&W Diesel does not publish an ISO 9001 or other quality-system certification on its site, which is unremarkable for an aftermarket distributor and remanufacturer of this size. The company frames quality through its remanufacturing process, component testing, and product support rather than a registered standard, and describes itself as one of the leading remanufacturing operations in North America. Buyers who require a documented quality system should confirm scope directly with the company.

Sourcing evidence

D&W's US ocean-import record is small and points inward to its rebuild operation rather than to finished-goods resale. Customs bills of lading show 137 sea shipments between January 2015 and July 2025, dominated by rotating-electric rebuild inputs: starter motors, armatures, field coils, brush holders, and blower motors, with some turbo compressors. That is the import profile of a remanufacturer buying cores and components, not a reseller landing containers of packaged product. The most active foreign suppliers on record:

Seven shown of the top suppliers on record. By origin, the mix leads with China, then Japan, Italy, Taiwan, and Singapore. Direct sea imports have been quiet since July 2025, which for a domestic distributor reflects US-based sourcing and episodic overseas component buys rather than a downturn. For buyers weighing supplier tiers and tariff exposure, the takeaway is that D&W's own overseas footprint is modest.

Coverage caveats: these are US ocean-freight records only. Air, truck, and rail movements do not appear; some records name freight intermediaries rather than manufacturers; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
