Diesel Repair Shop Serving Lebanon, OH
Complete diesel service for Lebanon and Warren County — pickup truck repair, performance tuning, heavy duty work, and equipment service from County Line Diesel Performance in nearby Harveysburg.
Warren County's Diesel Specialist.
Lebanon's been growing fast and the diesel population's grown right along with it — more contractors, more landscapers, more guys towing campers and trailers out of subdivisions on the weekends. What hasn't grown is the number of shops that actually specialize in diesel.
County Line Diesel Performance is about 20 minutes east of downtown Lebanon, an easy drive up SR-63 or 123. We're a real diesel specialist — not a general repair shop that takes diesel work when they can fit it in. From a daily-driven F-250 to a contractor's dump truck to a tractor for the back ten acres, we handle the whole spectrum.
Every Diesel Service.
One shop covers it. From routine maintenance to full builds.
Engine Repair & Rebuilds
Diagnostics, injector work, head gaskets, full rebuilds. Real diagnosis instead of guessing-and-replacing.
Performance & Tuning
Tunes, programmers, deletes, turbo upgrades, full power builds — for Cummins, Power Stroke, and Duramax pickup trucks.
Heavy Duty Trucks
Class 6, 7, and 8 commercial service, DOT inspections, fleet maintenance — for Lebanon's growing commercial operations.
Farm & Heavy Equipment
Tractors, skid steers, construction equipment, hydraulics. On-site service available across the area.
Diesel Done Different.
The dealership has the parts and the price tag. The corner shop might have the time. We aim for the best of both.
Diesel-Only Focus
This is what we do — not a sideline next to brake jobs and oil changes on gas cars.
Owner Operated
You talk to the wrench. No middle manager between you and the work.
Right-Sized Pricing
Honest labor and parts pricing. Estimates before work starts. No "shop fee" surprises.
Real Turnaround
Working trucks don't sit waiting weeks for a slot. We move jobs through and keep you informed along the way.
Lebanon Questions.
The stuff Lebanon folks ask most. Anything else, give us a call.
How far is your shop from downtown Lebanon?
About 20 minutes — straight shot up SR-63 east, or 123 north, depending on which side of town you're on. Easy drop-off in the morning.
Can you handle a fleet of trucks?
Yes — small fleets are a regular part of what we do. We can set up service intervals, track DOT inspection dates, and work around your dispatch schedule. Call to talk through what your operation needs.
Do you work on diesel SUVs and 1500-series trucks too?
Yes — newer half-ton diesels (1500 EcoDiesel, etc.) and diesel SUVs are absolutely part of what we work on. Whatever burns diesel, we'll take a look.
What's your usual wait for an appointment?
Depends on what's in the shop. Diagnostic and routine work can usually be slotted within a few days. Bigger jobs get planned around parts availability. Best to call and we'll give you a real timeline.
