The IAG Performance internal wastegate locking bracket is designed to replace the OEM TD04 Series Turbo wastegate actuator and lock the wastegate shut. This is the most versatile method of keeping your wastegate closed when switching to an external wastegate. The dual spherical bearing linkage makes installation a snap and can be easily reverted to a stock set-up. The center turnbuckle allows you to easily close the wastegate. Turning one direction lengthens the linkage. Turning the other way shortens it.
