Diesel Performance and Repair Shop in Nicholson, GA
Trusted Diesel Technicians in Nicholson, Georgia
Nicholson is home to contractors, poultry haulers, and diesel owners who expect more than a guess and an oil change. Trusted diesel work means technicians who have actually torn into a Duramax, PowerStroke, or Cummins before, not a general mechanic learning on your dime. Our Jefferson, GA shop is a short drive down GA-335, putting the area’s most experienced diesel specialist within easy reach of Nicholson.
Southern Built Auto Works runs on diesel and nothing else: Duramax, PowerStroke, and Cummins. No gas engines, no distractions — just the platform-specific expertise and the diagnostics Nicholson trucks need to stay dependable.

About Us
Southern Built Auto Works was built for the diesel community, not the general public. We work on Duramax, PowerStroke, and Cummins trucks exclusively, so Nicholson-area drivers get the same focused attention as anyone who walks through our door. From our shop on Athens Highway in Jefferson, just up GA-335 from Nicholson, we’ve built our reputation on fair pricing and diagnostics that get it right the first time.
Whether you need a tune and turbo replacement on your Duramax, a DPF cleaning on your PowerStroke, or a grid heater check on your Cummins, our techs diagnose before they replace parts, so you’re never paying for guesswork. We stand behind every job the same way we would our own truck. Nicholson customers make the drive because a shop that actually knows diesel saves money and headaches down the road.
