Heavy-Duty Truck Repair Services
Full-service Class 6–8 diesel repair across eight clusters — engines, emissions, drivetrain, brakes and air, electrical, chassis, compliance, and specialty work.
Emissions
DPF Cleaning & Forced Regen
When soot and ash load up faster than the truck can burn them off, regens get longer, power drops, and eventually the ECM derates you. We clean, diagnose, and force-regen on site — and tell you honestly whether the filter can be saved or needs replacing.

Engine Derate Diagnosis & Repair
A derate means the ECM has decided the truck can't be trusted to run at full power — pull over safely, don't keep pushing it, and call. We read the fault code, trace it to sensors, DEF quality, or the aftertreatment system, and get you back to full power instead of just clearing the light.

DEF & SCR System Repair
A DEF quality fault or an SCR efficiency code usually comes down to one of a handful of things — bad fluid, a failing sensor, a frozen line, or the catalyst itself losing efficiency after years of duty. We test each one separately instead of replacing parts until something clears.

EGR Valve & Cooler Repair
White smoke at startup and coolant that disappears without a visible leak is the classic sign of a cracked EGR cooler letting coolant cross into the exhaust. We pressure-test the cooling system to confirm it before anything comes apart.
