Garrett 772441-5002S PowerMax Turbo | Ford 6.0L Power Stroke | 2004-2007 | New

Garrett PowerMax GT3788VA turbocharger, part number 772441-5002S, for 2004–2007 Ford 6.0L Power Stroke engines. This is a performance upgrade, not a stock replacement — it uses a larger compressor wheel than the factory turbo and supports up to an additional 175 horsepower over stock. It installs as a drop-in, retaining factory engine electronics and the stock mounting pedestal with no exhaust modifications required.

Key Features

• Larger compressor wheel than stock, increasing maximum power range while keeping turbo speeds down for the same power output
• Supports up to an additional 175 HP over stock with no sacrifice in drivability
• Garrett patented Advanced Variable Nozzle Turbine (AVNT) design for increased compressor flow and boost response
• Nine movable vanes increase turbine efficiency across the range, from idle launch through peak torque
• Patented integral electro-hydraulic actuation with proportional solenoid for infinitely variable control
• Drop-in fit — retains factory engine electronics and mounting pedestal, no exhaust modification needed

Fitment gate — this is the later 6.0L turbocharger. 2003 and early 2004 trucks built on or before 9/28/2003 use a different unit; the PowerMax equivalent for those trucks is 777469-5002S. Check your engine build date, not just the model year, before ordering. 2004 model year trucks were built with both turbo designs.

Second fitment gate — this is a performance upgrade rather than an emissions-compliant stock replacement. Confirm it is legal for your intended use and location before ordering, particularly in California.

What to expect on arrival — Garrett notes that when a PowerMax is new, or has sat long enough for oil to drain from the center housing, the rotating assembly will move more than expected in the radial direction. This is normal and not a defect.

Conclusion

This is the Garrett PowerMax GT3788VA upgrade turbocharger for the 2004–2007 Ford 6.0L Power Stroke, supporting up to 175 horsepower over stock through a larger compressor wheel while retaining factory electronics and mounting. It installs as a drop-in with no exhaust modifications. Verify your engine build date is after 9/28/2003, since 2004 trucks were built with two different turbochargers.
