Why Wilkerson's
Tired of “big shop” treatment?
Most diesel shops let your truck sit two and three weeks before anyone even looks at it — and half the time they get the diagnosis wrong. We don't run that shop.
02/Promise
Dealership-level service.
Small-shop relationship.
Dealer-grade work without dealer pricing, appointment-only friction, or runaround. The same people answer the phone every time. Saturday hours so drivers can come when the week's done.
03/Promise
The parts counter most shops don't have.
Big-truck parts, on the shelf.
Alternators, radiators, sensors, air bags, wheel seals, brakes, filters, big-truck tires. Call ahead, we'll pull it. Open Saturday 7–noon for parts pickup.
Services
Covered from PM to inframe.
We work on diesel trucks — Class 7-8 tractors, day cabs, dump trucks, box trucks, diesel pickups, RVs, buses. Not sure if your job is in scope? Call and we'll tell you straight.

About
Twenty years of finishing the job.
The Wilkerson family has been working on diesel trucks in Mississippi for more than 20 years. Now on US-49 in Jackson — same name on the sign every year, same family answering the phone.
We're not the cheapest shop in town. We're the one you call second, after the cheap guy didn't fix it. And then we put our name on the invoice and stand behind it.
