The Derate That Can't Wait

A 5-mph derate on I-10 with a load due isn't a maintenance item — it's an emergency. Most derates we respond to trace back to aftertreatment faults, sensor failures or fuel issues that we resolve on the shoulder within hours, not days. Our service trucks carry diagnostic laptops with dealer-level software for the major engine platforms, so we read the actual fault, fix what's failed, and clear it properly — not just reset it so it returns in fifty miles.

Roadside First, Shop When It Counts

Our rule is simple: if it can be fixed safely and correctly on the roadside, it gets fixed on the roadside — injectors, turbos, fuel and cooling systems, sensors, belts and hoses are all regular shoulder repairs for us. When diagnostics show internal damage — liner scoring, bearing wear, head failure — we tell you straight, help arrange the move to our shop at 4235 St Stephens Rd, and complete the overhaul with a written estimate and warranty. No billing roadside hours against a job that was never going to finish there. That's the No Fix, No Fee principle.

Engines We Know Cold

Cummins ISX and X15, Detroit DD13/DD15/DD16, PACCAR MX-11/MX-13, CAT C13/C15, International A26 and MaxxForce — including the emissions-era quirks each platform is known for. If it's powered by diesel and rolls the Gulf Coast corridor, we've turned wrenches on it.

FAQ

Common Questions

Average emergency response in the Mobile metro is 18 minutes; corridor calls depend on your exact location. Dispatch gives you an honest ETA the moment you call (251) 234-4623.
Almost certainly yes — Cummins, Detroit, PACCAR, CAT, International and MaxxForce are our daily work. Tell dispatch your engine and fault codes when you call.
Yes — when the aftertreatment system is otherwise healthy. If the DPF is face-plugged or sensors have failed, a regen alone won't hold; we diagnose the root cause first.
It varies by engine and damage. After teardown inspection you get a written estimate before any machine work begins — no open-ended authorizations.

“Driving our brand-new Super C diesel home from Florida, sensors going off, the engine went into idle mode as we reached Mobile. We called Sergey and he made it to us within 30 min. He diagnosed the issues and fixed what needed fixing. The price was not what I was expecting — we anticipated paying an arm and a leg. Would MOST definitely recommend!”

“My Freightliner started stalling right after fueling up. Other mechanics said the fuel pump was dead and didn't even have one in stock. These guys arrived in about 40 minutes, hooked up the computer and found it was just a failed crankshaft sensor. They noticed oil inside the connector, cleaned everything out, swapped the sensor — and the truck fired right up! A huge thanks to the team!”

“Towing a fifth wheel on vacation, we blew the water pump on our Ram 2500 Cummins. These guys answered right away and arrived on site before either of the roadside services I PAY FOR called me back. New water pump, thermostat, serpentine — then a coolant line blew and they wouldn't leave us. Great communication the entire time. I run a fleet of trucks and know how hard mobile maintenance can be — they delivered.”
