Diesel Truck Repair in Franklin, OH
Straight-priced diesel work for Franklin's pickup trucks, work rigs, and commercial fleets — fast turnaround and honest labor from County Line Diesel Performance in nearby Harveysburg.
Trucks That Earn. Repairs That Last.
Franklin runs on working trucks. Plumbers, builders, landscapers, truckers, mechanics, and small operators — folks whose Ford or Ram or Chevy diesel is the difference between getting paid this week and not. When that truck breaks, sitting in a dealer service lane for two weeks isn't an option.
County Line Diesel Performance is about 20 minutes east of Franklin in Harveysburg. We work fast, we charge fair, and we don't pad a repair to make a quarter quota. Honest hourly rates, straight estimates, real fixes. The kind of shop you tell your buddy about because he's about to get hosed somewhere else.
Working Truck Repair.
The work that keeps a diesel earning instead of leaking, smoking, or sitting.
Engine Repair
Real diagnosis instead of part-cannon guessing. Injectors, head gaskets, leaks, sensors — fix what's broken, leave the rest alone.
Heavy Duty Trucks
Class 6, 7, 8 commercial truck work and DOT inspections — turnaround fast enough that you're earning, not waiting.
Equipment Work
Skid steers, mini excavators, dump trucks, and other working iron. On-site service available when bringing it in isn't practical.
Performance & Tuning
Tow more, run cooler, drive better. Custom tunes for working trucks that need to do more than haul groceries.
Straight Up. No Games.
You shouldn't have to be a mechanic to know whether your mechanic is being straight with you. Here's how we work.
Real Estimates
Before any wrenches turn, you know what it costs and what we're doing. No "while we were in there" surprise charges.
Working Truck Priority
If your truck pays the bills, it gets moved through fast. Sitting in line waiting on the dealer isn't an option.
Owner Operated
The person turning the wrench is the person you talk to. No middle layer between you and the truth about your truck.
Stand By It
We do the work right. If something we touched isn't right, we make it right. That's the deal.

How far is your shop from Franklin?

Can you turn a truck around in a day?
For a lot of jobs, yes — sensor swaps, simple leaks, brake work, DOT inspections. Bigger jobs need longer but we'll always give you a real timeline upfront so you can plan around it.
Do you work on dump trucks and roll-offs?
Yes — Class 7 and 8 vocational trucks, dump trucks, roll-offs, and similar work rigs are right in our wheelhouse.
Do you offer financing?
We don't do in-house financing for repair work, but we can work with you on payment timing for bigger jobs if it helps keep the truck moving. Talk to us — we'll figure something out.
