What We Do

Heavy-Duty Service, Done Right

From emergency breakdowns to scheduled maintenance, we keep your diesel powerplants running at peak performance.

Engine Rebuilds & Overhauls

Complete bottom-end work, head machining, and full rebuilds. We restore your engine to spec — not just running, but reliable.

Turbocharger Service

Turbo rebuilds, balancing, and replacement. Lost boost or excessive smoke? We'll get your spool back where it belongs.

Diesel Fuel Systems

Injector testing, pump servicing, and fuel delivery diagnostics. We clean, test, and recalibrate for clean combustion.

Diagnostics & Electrical

Advanced scan tool diagnostics, wiring repair, and electrical troubleshooting. We find the root cause — not just the symptom.

Preventive Maintenance

Scheduled PMs that catch problems before they strand you. Oil changes, filter service, fluid checks — done thorough, not rushed.

One truck or fifty — we work with owners and fleet managers to minimize downtime and keep every unit road-ready.
