Engineered for 2003 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Ford Excursion trucks equipped with the 6.0L Powerstroke diesel engine, this genuine Garrett GT3782VA Turbocharger is a 100% brand-new OEM direct replacement. Rebuilt or remanufactured units frequently suffer from recurring unison ring hang-ups, turbine wheel fatigue, and worn center housings; installing an authentic factory-new Garrett assembly restores original boost levels, quick throttle response, and lower exhaust gas temperatures.

Because Ford and International Navistar updated the 6.0L turbocharger mounting pedestal, compressor wheel sizing, and turbine blade pitch across production runs, selecting the correct engine build date or Engine Serial Number (ESN) is necessary for proper fitment. Each unit arrives as a complete assembly with a factory-calibrated VGT control solenoid valve and installation hardware, with no core return or core deposit required.
