Diesel USA Group Inc., has joined VIPAR Heavy Duty, bringing seven additional U.S. locations to the network.
Diesel USA Group provides a comprehensive portfolio of diesel engine products, including turbochargers, fuel systems, exhaust and emission components, electrical parts, filtration products and charged air products. The company also offers high value technical services, such as machining, diagnostics, DPF cleaning, component repair, remanufacturing and full service parts distribution.
“Diesel USA Group’s decades long commitment to technical excellence, deep industry expertise and strategically located facilities significantly strengthen our network’s ability to support customers nationwide,” says Joe Meyer, vice president of business development for VIPAR Heavy Duty. “By adding their proven capabilities in diesel engine products, diagnostics and remanufacturing, we are expanding both the depth and reach of the solutions we can offer to end-users.”

Founded in 1950 by World War II veteran Lloyd A. Bailey, Diesel USA Group began as Diesel Injection Service Company in Louisville, Ky. Bailey’s technical expertise and early involvement in the post war diesel service industry — including his participation in the first meeting of the Association of Diesel Specialists (ADS) in 1956 — helped shape the company’s trajectory and the industry at large.
In 2019, Diesel USA Group was acquired by Jasper Holdings Inc., parent company of Jasper Engines & Transmissions. VIPAR reports the company continues to operate as an independent brand within Jasper’s ESOP structure while retaining the leadership team that has guided its long term growth.
“In evaluating the opportunity, we recognized the value‑added benefits of aligning with VIPAR Heavy Duty’s established network and expanding access to complementary product lines. As we looked at our existing relationships with leading suppliers within the VIPAR Heavy Duty family, it became clear that joining as a stockholder would deliver significant mutual benefit,” says Jerry Mabis, corporate liaison at Jasper Holdings
Diesel USA Group has locations in Louisville, Ky.; Cincinnati and Columbus, Ohio; Indianapolis, Fort Wayne, and Crown Point, Ind.; and Fontana, Calif.
