Semi Truck Repair in Fontana
Few crossroads matter to American trucking like Fontana — and a tractor down here means freight standing still. Our shop works on Class 8 tractors mechanically from one end to the other: diesel engines, transmissions, differentials, driveline and chassis, backed by gear and machine shop depth deep enough to rebuild components other shops would simply replace.
Fontana, CA · Class 8 specialists
Heavy-duty mechanical work, from repair to full rebuild
That covers repairing and rebuilding engines, rebuilding transmissions and differentials, clutch and driveline jobs, and the chassis and body repairs that years of hauling freight eventually demand. Nothing gets priced until it has been inspected and documented, and nothing leaves until it has been tested.
