About Grit
Full Service. Full Time. Fully Committed.
Grit Diesel Maintenance & Repair is a full-service commercial diesel shop in Shepherdsville, Kentucky, built around a simple standard: dependable repairs, quality workmanship, and honest service.
How Grit Works
The name isn't decoration. Commercial diesel work is demanding, and the trucks that come through the shop are how their owners make a living. Grit's job is to keep that equipment working — and the whole operation is set up around it.
- Diagnose it straight. Up-to-date diagnostics for all makes and models, so the repair matches the problem.
- Fix it right. Quality workmanship on everything from routine maintenance to clutches and transmissions.
- Say it plain. Honest service and direct communication about what the truck needs and what it doesn't.
- Be reachable. A shop that answers during the day, and a service truck with 24-hour roadside assistance when it's after hours.
Keep you working.
Keep you moving.
Built for Commercial Operators
Grit serves owner-operators, trucking companies, fleets, and any business that depends on working trucks. The service list runs the full width of what commercial equipment needs: diagnostics, routine maintenance, brakes, A/C, tires and alignments with Bridgestone and Michelin national accounts, federal annual inspections, California CARB testing, DEF/DPF repair, clutch and transmission work, dump truck repair, container, and chassis work — plus mobile support when the truck can't make it in.
