Diesel engines power your livelihood, and we understand what that means. From minor repairs to major rebuilds, our technicians have the knowledge and experience to handle any diesel engine issue on Class 6+ vehicles.
Diesel Transmission Repair
Transmission problems can bring your operations to a standstill. We diagnose and repair transmission issues efficiently, getting you back to hauling loads instead of dealing with breakdowns.
Driveline and Gear Service
Your driveline transfers power from the engine to the wheels. Any issues here affect performance and fuel economy. We service differentials, u-joints, driveshafts, and gears to keep power flowing smoothly.

Electrical problems can be frustrating and hard to trace. Our technicians have the tools and training to diagnose and repair wiring issues, lighting problems, and electronic system failures. We'll get your truck's electrical systems working properly again.
Engine Overhaul and Replacement
When your engine reaches the end of its service life, we provide complete overhaul and replacement services. With our truck dyno on-site, we can test and verify performance before your truck leaves our shop.
Preventative Maintenance
Regular maintenance prevents costly breakdowns and extends your truck's lifespan. We offer comprehensive preventative maintenance programs with early drop-off and after-hours pickup options. We honor manufacturer warranties and offer extended warranty options for added peace of mind.
