Description

The MMR 400046 is a billet trigger reluctor wheel designed to replace the factory stamped steel component for Ford 4.6L and 5.4L engines. It features CNC machined precision for improved timing accuracy and higher strength to reduce deformity at high RPMs.

This trigger wheel is a crucial part of the ignition system, aiming to provide a cleaner trigger signal that increases possible RPM potential. It has been tested by Team MMR up to 10,000 RPM.
