About Us
Southern Built Auto Works was founded with a single purpose: to give diesel truck owners in Jefferson and across Jackson County a shop they can actually trust. We got tired of seeing diesel builds misdiagnosed and diesel owners upsold on unnecessary repairs by shops that treat a Duramax like any other engine. Our team specializes exclusively in diesel performance and repair — which means deeper knowledge, better diagnostics, and results that hold up under real-world conditions on GA-82 and beyond.
From our location on Jefferson Highway, we serve the entire Northeast Georgia corridor — Jefferson, Commerce, Athens, Gainesville, and everywhere in between. Whether you are looking for PowerStroke diagnostics and performance work on your daily driver or a full build on a show truck, we bring the same dedication to every vehicle that rolls through our doors. Southern Built Auto Works is not just a repair shop — it is a shop built by diesel guys, for diesel guys.
