Whether you’re towing, hauling, or just love the torque, your Cummins engine deserves a team that knows how to keep it running clean and strong.

Serious Power. Serious Know-How. We Know Your Cummins.
You don’t drive a Cummins because it’s cute—you drive it because it works hard. That’s why we bring real diesel experience to every Dodge truck we service. At Jefferson Auto Service, we understand how Cummins engines operate under load, how they wear, and where problems tend to start. From turbo diagnostics and EGR service to glow plugs, sensors, and high-pressure fuel systems—we’ve got it covered.
We’re also one of the few local shops that blend old-school wrenching with modern digital diagnostics. You’ll get a full Digital Vehicle Inspection (DVI) before we do anything, and we’ll show you exactly what’s happening with your truck—no guesswork, no pressure. Just smart, diesel-savvy repairs to keep your RAM running at its best.
