What are cam phasers? Chrysler’s cam phasers are specially designed, computer controlled cam gears that have the ability to adjust camshaft position while the engine is running. They are used on all 2009 5.7L and 2011 6.4L newer engines. How do they work? Engine oil is pressure fed through a series of passageways in the cylinder heads and camshafts, out to the cam phasers. The engine computer controls a pair of solenoids that adjust this oil flow into, and out of, a series of chambers inside the cam gears. Located inside these chambers are vanes, attached to a spring-loaded central hub. The hub is directly attached to the camshaft, and as oil is allowed into and out of these chambers, the position of the cam can be retarded up to 38 crankshaft degrees. 

What does COMP’s cam phaser lock kit do? COMP’s Cam Phaser Locks is a precision made spacer that installs into the cam gear’s oil chambers. This spacer takes up all the volume that would normally be used by the factory cam gear for movement. By installing the cam phaser limiter, the cam design window opens up, allowing you to install big powerful camshafts with safe piston to valve clearances.
