Camshaft phasers are computer-controlled cam gears that automatically advance, or retard camshaft timing based on engine RPM. They are used on Gen 5 (LT-based) Variable Valve Timing (VVT) engines.
While this technology provides fuel efficiency and the ability to always be in the best position for maximum power regardless of engine RPM, it does present limitations when it comes to performance cams. With such a wide range of valve timing movement, there is very little piston-to-valve clearance, which limits you to small cam profiles.
Phaser Limiter Kits restrict the range of cam timing movement. This will allow the necessary valve clearance for serious performance cams with more duration and tighter lobe separations.
