Product Description

The Garrett 772441-5002S PowerMax GT3788VA Turbocharger is a performance-oriented replacement turbo designed specifically for the Ford 6.0L Powerstroke diesel engines from 2004 through 2007. Built around Garrett's advanced AVNT™ variable turbine geometry technology, this turbocharger features nine movable vanes that optimize exhaust flow and boost delivery across the RPM range, enhancing throttle response, torque, and overall engine performance. The larger compressor and turbine wheel sizes improve airflow capacity compared to the stock unit, helping deliver stronger boost and power when paired with proper tuning.

This turbocharger is engineered as a **direct-fit replacement**, retaining the factory electronic actuator and mounting points for a straightforward installation. Its increased flow capability supports power gains over the original equipment turbo, making it suitable for daily driving, heavy towing, and higher-output builds on the Powerstroke platform. While primarily a drop-in unit, additional tuning and supporting modifications (such as fueling and intercooling upgrades) are recommended to fully realize the performance potential of this turbocharger.
