About Us

Heavy-Duty Truck Repair Built Around Uptime

LS Truck Repair keeps commercial trucks and trailers working — in the shop, at your yard, and on the roadside where service is available.

LS Truck Repair is an independent heavy-duty truck and trailer repair provider serving the Dallas area and the surrounding DFW freight corridors. The work covers what keeps Class 7 and Class 8 equipment moving: diesel engine repair, air brakes, drivetrain, steering and suspension, electrical and lighting, cooling and A/C, diagnostics, and full trailer service.

Commercial trucks do not break down conveniently. Because of that, service is structured three ways — scheduled shop work, mobile service at your yard or terminal, and roadside repair when a truck is disabled and service is available in that area.

For fleets, the same capability turns into scheduled preventive maintenance: PM intervals, DOT inspection readiness, and a repair history that makes downtime predictable instead of surprising.

We are an independent shop. That means no manufacturer quota driving the recommendation — just what the truck needs, what it will take, and what it will not.

  • Diagnose before replacing parts

    Guessing at parts is expensive and it does not fix trucks. We identify the actual cause first — with scan tools where it helps and hands-on troubleshooting where it does not.

  • Straight answers about scope

    If a repair cannot be done safely on the roadside, we say so and help you plan the tow instead of burning hours on the shoulder.

  • Built around uptime

    Every decision is weighed against how quickly the truck can go back to work without creating a repeat failure down the road.

  • Drivers, owner-operators and fleets

    One-truck operators get the same attention as fleet accounts, and fleet customers get maintenance records they can actually plan around.
