• Primary Category: Auto Repair & Service Shops for Sale

Overview

A confidential, independently owned diesel injection specialist located in San Bernardino County, California is available for acquisition. The Company focuses exclusively on fuel injector and injection pump testing, repair, and rebuilding, serving the heavy-duty trucking industry and related applications.

Situated in the Inland Empire, one of the busiest logistics regions in the United States, the business benefits from unparalleled exposure to fleets, owner-operators, and logistics companies that operate thousands of diesel-powered trucks daily.

This opportunity offers buyers a specialized niche, strong market fundamentals, and room for scalable growth.

Services & Customers

The Company specializes in:

Testing and rebuilding diesel injectors.

Diagnostics and rebuilding of injection pumps.

Precision calibration, cleaning, and quality assurance.

Customer segments include:

Independent owner-operators seeking affordable, fast turnaround.

Regional fleets in freight, construction, and municipal services.

Other diesel shops outsourcing injector and pump work.

Location Advantage

San Bernardino County lies at the center of Southern California’s Inland Empire logistics hub, with direct freeway access (I-10, I-15) and proximity to the Ports of Los Angeles and Long Beach. This ensures a steady stream of demand from trucking companies that rely on efficient maintenance to minimize downtime.

The region hosts millions of square feet of warehousing and distribution facilities, underscoring the long-term relevance of diesel services in the area.

Operations

The Company operates from a facility designed for specialized rebuilds, including test benches, ultrasonic cleaning equipment, and dedicated workstations. Workflows are standardized: inspection, testing, cleaning, reassembly, calibration, and QA before return to the customer. The business has a history of a strong client base with repeat customers from diesel mechanics to owner operators.

Operating hours include weekdays with limited Saturday availability—an advantage for drivers needing weekend service.
