Why call us first
Downtime is the only real cost
A truck sitting on the shoulder isn't just a repair bill — it's a missed delivery, a frustrated broker, and a driver burning hours. Everything we do is built to shorten that window.
Straight answers
You get the diagnosis, the price, and the realistic timeline before we turn a wrench. If it's a shop job, we tell you that instead of billing you to find out.
We know the pressure
We come out of freight, not just wrenching. We understand detention, appointment windows, and what a rolled load actually costs you.
What we fix
Road service, done properly
The work we handle on-site today. Anything beyond mobile scope, we'll say so up front.
01
Roadside breakdowns
Jump starts, no-starts, fuel delivery, lockouts, and getting a stopped truck diagnosed fast.
02
Engine diagnostics
ECM fault codes pulled and interpreted on-site — derate, check engine, and sensor faults.
03
Air brakes & air systems
Chambers, lines, valves, dryers, and leak-downs that keep a unit from releasing.
04
Electrical & charging
Batteries, alternators, starters, grounds, and the wiring faults that cause phantom problems.
05
Tire & wheel service
Road-service tire changes, blowouts, and wheel-end issues on tractor and trailer.
06
Cooling & DPF
Overheats, coolant leaks, hoses, plus aftertreatment and regen-related faults.
07
Trailer repair
Lights, ABS faults, landing gear, air lines, and door and latch problems.
08
DOT inspections
Annual inspections and pre-trip corrections so a unit goes back out legal.

Where we're headed
Mobile today. A full heavy-duty shop next.
4S Truck Center started mobile because that's where the need is most urgent — a truck down on the road can't drive itself to a bay. But mobile has a ceiling, and we've hit the point where the jobs we have to turn away are the ones worth building for.
We're actively scouting a location for a full heavy-duty shop: lifts, bays, alignment, and the kind of work that can't be done on a shoulder. Mobile service isn't going anywhere when it opens — it becomes the fast end of a bigger operation.
What the shop adds
Major engine & drivetrain — teardowns that need a lift and a clean floor.
Alignment & suspension — proper geometry, not a roadside guess.
Scheduled PM programs — fleets on a real maintenance calendar.
Overnight turnarounds — drop it after the run, pick it up ready.
Down right now?
Call the dispatch line and tell us the unit, the location, and what it's doing. We'll tell you straight away whether we can roll and how long we'll be.
