Phaser Limiter Kit, for Hemi 5.7,6.1,6.4

Cam phasers are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on the current engine rpm. Engine oil is pressure fed to the cam phasers through a series of passageways in the cylinder heads and camshafts. The engine computers control solenoids that adjust this oil flow into and out of the phaser's control chambers, giving the ability to retard the cams up to 60 crank degrees.

For Chrysler 5.7/6.1/6.4L Hemi engines; Automatically optimize camshaft timing based on the current engine rpm; Restricts the range of cam timing movement to only 14 degrees, thus providing the necessary valve clearance for serious performance cams with tighter lobe separations ? all while still utilizing the benefits of VVT technology
