We bring the shop to you
Mobile diesel repair built for Central Arkansas
When a semi, an 18-wheeler, or a heavy work truck quits around Little Rock, the default plan is a wrecker and a wait in a shop line. We cut out both. Little Rock Mobile Diesel sends a diesel mechanic in a stocked service truck directly to the truck — the shoulder of I-40 or I-30, the truck stop lots at Galloway or off I-30 at Otter Creek, a warehouse dock near the port, or a jobsite in Saline or Faulkner County.
Most breakdowns come down to parts that can be replaced right where the truck is parked: air lines and brake chambers, tires, batteries and starters, belts and hoses, fuel filters, and emissions sensors. We run 24/7 roadside assistance, mobile semi truck repair, commercial tire service, diesel diagnostics, and trailer repair — along with DOT inspections and fleet PM in your yard.
Owner-operator passing through on I-40, or a local fleet running out of North Little Rock — you get the same number and the same answer: a mechanic on the way, day or night.

Our interstates
Where Arkansas’s interstates come together
Little Rock is the one place in Arkansas where I-40, I-30, and I-57 all meet. East–west freight between Oklahoma City and Memphis, southwest traffic to Texarkana and Dallas, and the I-57 run toward St. Louis all squeeze through North Little Rock and across the Arkansas River here.

Questions
Mobile diesel mechanic FAQ
Do you come to my truck, or do I need a tow?
We come to you. A mobile diesel mechanic drives to the truck — interstate shoulder, truck stop, yard, dock, or jobsite — and repairs it there whenever the job can be done on site. If it really needs a shop, you’ll hear that up front so you can call a wrecker without losing more time.
Are you actually open 24 hours?
Yes. Dispatch answers 24 hours a day, 7 days a week, 365 days a year — overnight, weekends, and holidays included.
What kinds of trucks do you work on?
Class 6 through Class 8 diesel trucks — semis, straight trucks, and heavy work trucks — and the trailers behind them: Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, and Western Star tractors, plus day cabs, yard tractors, box trucks, dump trucks, reefers, dry vans, and flatbeds.
How much does a mobile diesel mechanic cost?
It depends on the repair, the parts, the drive to your truck, and the time of day. Describe the problem and your location on the call and ask for pricing before the mechanic heads out.
How fast can a mechanic get to me?
That depends on where the truck is and on traffic — the I-30/I-40 interchange, I-630 at rush hour, and I-40 through North Little Rock can change drive times a lot. Dispatch gives you an estimated arrival time on the call.
Is there a mobile diesel mechanic near me?
If your truck is anywhere around Little Rock — Pulaski County, the I-40, I-30, and I-57 corridors, or the cities along them — yes. Call (501) 263-2565 with your location and dispatch will send a mechanic.
What areas do you serve?
Little Rock and North Little Rock, plus Conway, Benton and Bryant, Jacksonville and Cabot, Sherwood, Maumelle, and Searcy. See all service areas.
Can you handle DOT inspections and fleet maintenance?
Yes. On top of breakdowns, we do DOT inspections and preventive maintenance at your yard, so trucks stay working instead of waiting at a shop.
