Columbia’s Diesel Repair Experts – Built on Experience. Backed by Integrity.
At Road 1 Inc, we’re more than just a repair shop — we’re the diesel partner trusted by owner-operators, fleets, and businesses across South Carolina. With a certified team, state-of-the-art equipment, and a commitment to service that never sleeps, Road 1 is built to keep your trucks on the road and your business moving.
Our Story
Road 1 Inc was founded to solve a common problem in the heavy-duty industry: too many repair shops take shortcuts, overcharge, or leave drivers waiting. We decided to do things differently. From day one, our goal has been simple — deliver dealership-quality service without the wait, price tag, or runaround.
What started as a mobile diesel repair unit has grown into one of the Midlands’ most respected full-service diesel repair operations, with a dedicated shop in West Columbia and a fleet of mobile service trucks serving a 60+ mile radius.
