Cam Phaser VVT Limiter Kit For '09+ GM Gen IV LS And '14+ GM Gen V LT1

Cam phasers are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on the current engine rpm. Currently they are used in all 2005 and newer Ford Modular 3 Valve and all 2007 and newer GM L92 engines. 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 GM Gen IV 2007-2008 VVT applications; Automatically optimize camshaft timing based on the current engine rpm; Computer controls the oil flow in and out of the phaser's chambers giving the ability to retard the cam up to 52 degrees
