Fleet Maintenance & PM Programs in Jackson, MS
Wilkerson's runs fleet maintenance programs for diesel operations from owner-operators up through 50-truck fleets out of our Jackson, MS shop on US-49. A real PM program — scheduled intervals tied to your engine hours and miles, priority scheduling, consolidated monthly billing, a dedicated point of contact who knows your fleet by name.
Heavy-duty trucks average 8.7 unplanned downtime days per truck per year. Fleets that follow a strong PM program cut that by about 20%. At $700–$1,000 a day in lost revenue per truck, the PM math works on every truck you run. We make the downtime math work.
We service multi-brand fleets — Cummins, Detroit Diesel, CAT, Paccar, International, Volvo on the engine side, and the major chassis brands. One phone number, one name on every invoice, one PM schedule that follows the truck.
What's included
Everything we do on a fleet maintenance visit.
Scheduled PM intervals
Tied to engine hours and miles — your manufacturer interval, not a sticker on the windshield.
Priority scheduling
Fleet trucks jump the walk-in line. We hold morning bays for fleet accounts.
Consolidated monthly billing
One invoice per truck or one combined per month, PO-friendly.
Dedicated contact
Same name on the phone every time. You don't re-explain the fleet to a new service writer.
Service log per truck
Real maintenance history — yours, not ours. Pays for itself when you sell, refinance, or hand a truck to a new driver.
Common-failure parts on shelf
Alternators, sensors, air bags — tagged to your account through our parts counter.
DOT compliance support
Annual DOT inspections and pre-CVSA Roadcheck prep, in-house.
After-treatment health monitoring
Catch a NOx-sensor or DEF-heater failure before it derates a truck on the road.

Run the numbersPricing & estimates
No surprises on the invoice.
Fleet programs are scoped to how your fleet actually runs — engine families, common failures, monthly volume. Call (601) 414-0878 to set up a 20-minute fleet intake. We’ll quote a PM program and parts account that fits.
Our process
No surprises between the call and the invoice.
Four steps from the first call to the keys back in your hand. No mystery, no upsell theater.
- 01/Step
Call us
A real person answers the phone. We'll tell you straight whether your job is in scope and book you in if it is.
- 02/Step
Written estimate
We diagnose and write up the work before we touch anything billable. You see the price and the parts before you approve.
- 03/Step
You approve
Nothing happens without a green light from you. If we find more during the repair, we stop and call before we keep going.
- 04/Step
Repair + written warranty
Same name on the invoice every time. Our own written warranty on covered work — and the family promise behind it.
Why Wilkerson's

- 7am–noon
- Saturday
Fleets running a strong PM program see ~20% fewer unplanned downtime days. Industry data, not a marketing pitch.
Trucks, tires, parts, DOT — all under the same roof, same phone, same family. No coordinating across vendors.
Saturday morning is open for light PM and parts pickup. Some fleets run their PM on Saturdays so the trucks run during the week.
Frequently asked
What people ask before they bring the truck in.
Tap any question to expand the answer.
It depends on fleet size, engine families, duty cycle, and how heavy the PM schedule is. Call (601) 414-0878 and we'll book a 20-minute fleet intake — by the end of the call we can quote you a real program. No upfront commitment.
Owner-operators with one truck up through 50-truck operations. The program is the same — it just scales. If you've got two or three trucks running on a similar schedule, you're already a fleet for PM purposes.
Yes. Annual DOT inspections in-house. We also do pre-CVSA Roadcheck prep — catch the small stuff before a roadside officer does, then write it up cleanly so you've got the paper trail.
Yes. Whoever calls in, we'll work with. The dedicated-contact piece on our end means you get the same Wilkerson service writer every time, but if you've got someone managing maintenance internally, we'll talk to them directly.
Yes — fleet parts accounts can include trucks that don't get serviced at Wilkerson. Common-failure parts tagged to the account, consolidated monthly billing on parts only. Call to set it up.
