Engine Services We Provide
Minor Engine Repairs
Not every engine issue requires a full teardown. We handle turbocharger replacements, injector service, valve adjustments, oil leaks, gasket replacements, and sensor diagnostics. Our goal is always the most cost-effective repair that gets your truck earning again.
In-Frame Overhauls
When your engine has hit high miles but the block is still sound, an in-frame overhaul replaces pistons, liners, rings, bearings, and gaskets without removing the engine from the chassis. This saves significant labor time and cost while restoring compression, power, and fuel economy.
Engine Conversions & Swaps
Looking to upgrade your powertrain or replace a failing engine with a different platform? We handle complete engine conversions including wiring harness adaptation, ECM programming, and emissions system integration. We'll help you evaluate whether a conversion makes sense for your fleet's needs and budget.
