Truck Repair Service
Semi Truck Repair
Mechanical, electrical and air system repair for tractors and sleeper units.
A semi tractor is a system of systems: a diesel engine, an air brake network, a heavy drivetrain, a high-current electrical system and a cab full of sensors that all have to agree with each other. LS Truck Repair works across those systems on day cabs, sleeper units and tractors used in regional and over-the-road operations.
Work starts with an honest diagnosis. Codes are pulled, the symptom is reproduced where possible, and the actual cause is identified before parts are replaced — because on a Class 8 truck, guessing is expensive.
