Semi-trucks and Class 8 tractors demand specialized expertise. Engine power, air brake systems, transmission complexity — it is a different league from light-duty work. We repair Freightliner, Peterbilt, Kenworth, and Volvo semis on I-80. Cummins, Detroit, and PACCAR power. Call +1 308-270-3596 and we will diagnose and repair your semi roadside.
Every system on a semi-truck. Engine diagnostics and repair. Transmission and driveline. Air brakes and electrical. All diagnosed with factory tools and repaired roadside when possible.
Cummins, Detroit, PACCAR engines. Fuel systems, emissions (DEF, SCR, DPF), turbo, EGR. Diagnostics and roadside repair.
Allison, Eaton Fuller, and manual transmissions. Shift problems, pressure issues, solenoid faults. Diagnosis roadside.
Compressor, brake valves, solenoids, chambers, and ABS control modules. Air system problems are safety critical.
Alternators, starters, wiring, and control module diagnostics. 24V electrical systems and integrated controls.
Drive shafts, U-joints, wheel bearings, and differential issues. Trailer connections and kingpin wear.
Overheating, water pumps, thermostats. Fuel system diagnostics, gelled fuel treatment, filter service.
A semi-truck is a 70,000+ pound integrated system. The engine pushes 400 horsepower. The transmission handles 1,400+ pounds of torque. The air brake system runs at 120 PSI across multiple circuits. The electrical system is 24V and computer-controlled. Every component depends on others.
When a semi goes down on I-80, the breakdown often cascades. A fuel pressure fault triggers shift failures. A battery issue cuts alternator charge. An air leak affects braking. Without diagnostic tools and experience, you are guessing.
We have Class 8 training, factory diagnostic software, and parts in stock. We know how these trucks are built. We diagnose and repair complex failures on the road. Call +1 308-270-3596 with your truck details.
Class 8 refers to trucks over 33,000 lbs GVWR — standard over-the-road tractors. Repair covers engines (Cummins, Detroit, PACCAR), transmissions, air systems, and all supporting components.
Class 8 semis have higher pressures, more complex systems, and require specialty tools. A semi engine runs 400+ hp and 1,400+ lb-ft torque. Air brakes run 120+ PSI. Transmissions handle extreme loads.
$400–$1,200 for most mobile repairs. Complex engine work, transmission diagnostics, and brake system jobs run higher. We provide quotes before work starts.
We diagnose transmission problems — shift issues, pressure faults, solenoid failures. Some fixes happen roadside. Complex rebuilds require a shop. We advise upfront.
Yes. Freightliner, Peterbilt, Kenworth, Volvo, Mack — we service all Class 8 trucks. Cummins, Detroit, PACCAR engines. Allison, Fuller, and other transmissions.
24/7 Class 8 truck repair — all brands, all systems.
