Kingman Diesel, Truck & Trailer Repair: The Only Shop in the Area That Does It All
At Kingman Diesel, Truck & Trailer Repair, we understand that downtime costs money. That’s why fleet managers, owner-operators, and local businesses trust us to keep their heavy-duty trucks and engines running reliably — regardless of make, model, or complexity. We’re proud to be the only full-service shop in the region capable of complete diagnostics and repairs on all heavy-duty truck brands and engines, and the only facility equipped to perform CARB (California Air Resources Board) emissions testing when you need it.
Why one shop for every make and model matters
Broad experience reduces errors: Different manufacturers use different control systems, sensors, and diagnostic logic. Our technicians are trained and certified to handle Detroit, Cummins, Caterpillar, Volvo, PACCAR, MAN, and other major heavy-duty engine platforms. That means faster, more accurate troubleshooting and fewer repeat repairs.
Unified documentation and parts sourcing: We maintain up-to-date technical manuals, OEM software, and parts channels for every brand. That streamlines repairs and shortens turnaround time, keeping your trucks on the road longer.
Fleet consistency and accountability: Working with a single trusted provider simplifies maintenance records, warranty coordination, and preventive-service scheduling for mixed fleets.
Comprehensive diagnostic capabilities
Advanced electronic diagnostics: We use OEM-grade scan tools and software to read fault codes, perform active tests, calibrations, and module programming across virtually all heavy-duty platforms.
Full-system troubleshooting: Our diagnostics address engine, transmission, ABS, DPF, SCR, EGR, turbocharger, fueling systems, and vehicle networks so we can find root causes rather than chasing symptoms.
Real-world testing: We perform road tests, load-testing on forklifts and hoists where applicable, and use data-logging to confirm repairs under operating conditions.
Complete repair services — engine to trailer
Engine overhaul and replacement: From minor repairs to complete rebuilds or drop-in replacements, our shop handles it with precision.
Fuel systems and injectors: We service and test high-pressure common-rail systems, unit injectors, pumps, and injectors per OEM specs.
Emissions systems and aftertreatment: Repair and maintenance for DPF, SCR, AdBlue/DEF systems, and EGR to ensure compliance and performance.
Transmission and driveline: Rebuilds, diagnostics, and repairs for automated and manual heavy-duty transmissions and driveline components.
Brake systems and air systems: ABS diagnostics, air system repairs, compressor and dryer service, and full brake overhauls.
Trailer services: Electrical, braking, suspension, and structural repairs for semi-trailers and heavy trailers.
CARB emissions testing — certified and capable Kingman Diesel is equipped and trained to perform CARB emissions testing and repairs for diesel heavy-duty vehicles. We understand California’s strict emissions standards and how they impact interstate fleets and vehicles returning to CARB-regulated jurisdictions. Our CARB services include:
Pre-test diagnostics and repairs: We identify and correct issues that would cause a failed emissions test, including aftertreatment faults, sensor failures, and fuel system problems.
Official CARB testing: Performed using approved equipment and procedures to provide accurate, compliant results.
Emissions system documentation and certification: We provide the records and certifications required for compliance and fleet audits.
