The Power Heavy Duty network has added American Truck Parts, a full-service heavy duty truck and trailer service and parts provider based in Porterville, Calif.
American Truck Parts offers comprehensive in-house service capabilities, including a full-service truck and trailer service department, flywheel resurfacing, driveline services, hydraulic hose fabrication, mobile truck repair and machine shop services.
Strategically positioned near major freeways in California’s Central Valley, the company says it supports a diverse customer base across on-highway, off-highway, industrial and agricultural applications, serving fleets and owner-operators in the heart of one of the nation’s most active agricultural regions.
Owner and president Brandon Tharp leads a staff of 12 including four technicians, two counter staff and one outside sales representative.
“Our vision is to continue building a strong, reliable truck parts and service operation that our customers can depend on day in and day out,” says Tharp. “We’re focused on expanding our parts inventory, growing our service capabilities and strengthening our presence throughout the Central Valley. At the same time, we want to stay true to our roots providing honest service, building long-term relationships and continuing the legacy our family has built in this industry.”

Tharp purchased the business in 2025 but is no stranger to the trucking and heavy-duty parts industry.
The roots of American Truck Parts are closely tied to a long-standing Central Valley trucking and heavy-duty tradition. The Tharp family’s involvement in trucking dates back to 1935, when E.M. “Gene” Tharp began his career in commercial hauling. Over the decades, the family’s operations expanded into truck sales, service and parts, ultimately leading to the formation of American Truck Parts in 1979. From there, after a series of acquisitions, American Truck Parts became available as an independent business opportunity.
Today, American Truck Parts continues that legacy as an independent operation focused exclusively on parts and service, while remaining connected to generations of industry experience, the company says.
“American Truck Parts and their broad service capabilities, strong regional presence and commitment to supporting mixed-vocation customers make them an excellent fit for our growing network,” says Joe Meyer, vice president of Business Development for the VIPAR Heavy Duty Family of Companies. “The Tharp family legacy provides a strong foundation, and Brandon’s leadership brings fresh perspective and momentum that position the business well for long-term success.”
