Class 8 tractors & DOT readiness
Commercial Truck & Semi Inspection
A truck that can't pass DOT can't earn. We inspect to the inspection — brakes, after-treatment, and frame — before it costs you a load.
Class 8 trucks live and die on their brakes, after-treatment, and frame. A pre-purchase inspection here doubles as a DOT readiness check: we measure brake stroke, scan the after-treatment system, and verify the truck won't strand you with an out-of-service violation the week after you buy it.
What we inspect
- Engine & after-treatment diagnostics (DPF, DEF, regen history)
- Air brake system: leak-down, push-rod stroke, lining thickness
- Frame, crossmembers, and 5th wheel for cracks, rust, and repairs
- Steering, king pins, tie rods, and front-end play
- Drivetrain: clutch, transmission, differentials, and U-joints
- Tires: tread, age, matching, and DOT-legal depth on all positions
- Suspension, air bags, and ride-height systems
- Cab, sleeper, HVAC, and electrical/lighting
- Fluid condition and coolant/DEF quality
- DOT-style walkaround against out-of-service criteria
