Diesel USA Group Brings Turbocharger Expertise to the VIPAR Heavy Duty Distributor Network
Diesel USA Group Inc., a long established leader in diesel engine products and services, 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.
Founded in 1950 by World War II veteran Lloyd A. Bailey, Diesel USA Group began as Diesel Injection Service Company in Louisville, Kentucky. 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. 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.
Jerry Mabis, Corporate Liaison at JASPER Holdings Inc., explained that Diesel USA joined VIPAR Heavy Duty to leverage its long‑standing position as a central distributor of fuel‑injection, turbocharger, and engine‑related fuel‑system component product lines.
"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," said Mabis.
Diesel USA Group serves a diverse customer base across industries that rely on gas and diesel engine systems. Its market reach extends nationwide through locations in Louisville, Ky.; Cincinnati and Columbus, Ohio; Indianapolis, Fort Wayne, and Crown Point, Ind.; and Fontana, Calif. These facilities enable the company to deliver fast, reliable products and technical expertise to commercial fleets, consumer diesel drivers, and equipment owners demanding trusted performance and support.
“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. 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,” said Joe Meyer, Vice President of Business Development for VIPAR Heavy Duty.

VIPAR Heavy Duty Chairman of the Board Bill Nolan Inducted into the Heavy Duty Aftermarket Hall of Fame
The VIPAR Heavy Duty Family of Companies is proud to announce that Bill Nolan, President & CEO of PBS Truck Parts and Chairman of the Board at VIPAR Heavy Duty, has been inducted into the Heavy Duty Aftermarket Hall of Fame. Nolan received the honor Jan. 20 during the Heavy Duty Aftermarket Week (HDAW) General Session in Grapevine, Texas.
Founded in 1952 as the Power Brake and Spring Company, the business was acquired by Nolan’s family in 1973. Nolan contributed immediately, working part‑time as general labor, shop labor, delivery driver, and counter salesperson. He became Financial Controller in 1984, and assumed the role of President in 1989, succeeding his father. Under his leadership, the company evolved into PBS Truck Parts and has modernized operations, expanded to seven locations within Indiana and Michigan, and strengthened its reputation as a trusted, family‑owned distributor.
Nolan has been a member of the VIPAR Heavy Duty Board of Directors since 1994 and has served as Chairman since 2011. During his tenure, VIPAR Heavy Duty has experienced significant growth and transformation, including the acquisition of Power Heavy Duty, the opening of Global Parts Network, and the development of a robust digital ecosystem. The network has expanded to more than 1,000 locations and extended its footprint into Central and South America.
Beginning with a heartfelt thanks to his wife, daughters, and sons-in-law, Nolan moved on to acknowledge the peers and mentors in the industry who have supported and encouraged him.
“I would like to thank my family and friends at VIPAR. I've benefitted from the cohesive teamwork that has made VIPAR Heavy Duty a success over the years,” he said, mentioning David Rex, Elmer Bower, Harvey Peterson, Steve Crowley, and current VIPAR Heavy Duty President and CEO Chris Baer. “VIPAR is the backstop that helped keep our company independent. It has kept us in the game, and made us more competitive. The future looks bright.”
“Bill’s leadership has been instrumental not only to PBS Truck Parts, but to the entire VIPAR Heavy Duty network,” said Baer. “His deep industry knowledge, unwavering integrity, and passion for supporting independent distributors have helped strengthen and elevate the heavy‑duty aftermarket. Bill embodies the values of our organization, and his induction into the Hall of Fame is a well‑deserved recognition of his decades of dedication and impact to the industry.”
Nolan also credited the staff at PBS Truck Parts for consistently rising to meet every challenge.
He concluded with remarks that carried particular significance, coming from a newly inducted Hall of Fame member.
“For all of you young people, it's up to you. It's up to you to keep networking with your peers, to develop long lasting relationships, to become leaders of your organizations. Give it all you've got. The time will pass in the blink of an eye, but the friendships will last a lifetime. To distributors, keep getting better. Work on your succession plans. Do everything you can to remain independent. After all, we are the foundation of the aftermarket.”
The Heavy Duty Aftermarket Hall of Fame recognizes exceptional leaders whose achievements, vision, and commitment have meaningfully advanced the heavy‑duty aftermarket industry. The ceremony is a highlight of the annual HDAW Conference, which is owned and operated by the Auto Care Association, Commercial Vehicle Solutions Network (CVSN), and MEMA Aftermarket Suppliers.
