About Us
Southern Built Auto Works was built for the diesel community — not the general public. Athens and Clarke County have no shortage of trucks hauling loads down US-78 and Commerce Road, and every one of those owners deserves a shop that can diagnose a diesel fault accurately without guessing, upselling, or wasting time. Our team focuses exclusively on diesel performance and repair, which means every technician in our shop has deep platform knowledge that a generalist simply cannot match.
From our location on Jefferson Highway — just up US-441 from Athens — we are the diesel specialist that Clarke County drivers have been looking for. Whether you need a tune, a turbo swap, an EGR delete, or full duramax diesel performance upgrade on your daily driver, our shop brings the same level of commitment to every build. We are not just fixing trucks — we are building relationships with the Athens diesel community one satisfied customer at a time.
