The Brenspeed phaser lockout kit for 5.4L/4.6L 3V engines permanently
fixes variable valve timing. It stops the famous ticking and rattling
noise caused by worn factory phasers..
How It Works
Blocks
movement: The metal wedges fit tightly inside the factory cam phaser
mechanism.
Zero
rotation: It locks the camshaft into a single fixed position (usually
fully advanced).
Stops
noise: It ends the destructive knocking and rough idle linked to loose
or failing internal phaser parts.
