Restore proper boost control and turbo performance on your late 1999.5–2003 Ford 7.3L Powerstroke with this genuine OEM Garrett wastegate actuator. Designed as a direct replacement for stock GTP38 and GTP38R turbos, it regulates the internal wastegate to maintain correct boost levels and prevent over-speeding of the turbine.

A failed or leaking wastegate actuator is a common cause of poor boost, reduced power, and increased exhaust temperatures on high-mileage 7.3 Powerstrokes. Replacing it with this genuine Garrett unit returns factory-like response and durability without aftermarket modifications.
