COMP Cams Cam Phaser Limiter Kit 2014-2018 GMC Sierra 1500 5.3L & 6.2L

COMP Cams Cam Phaser Limiter Kit

*Fits: 2014-2018 GMC Sierra 1500 5.3L or 6.2L

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.

Features:

• Retains VVT functions
• 20 degree limit
• Restricts cam phaser motion
• For use with High Performance camshafts

While this technology provides tremendous efficiency benefits, such as fuel efficiency and the ability to always be in the best position for maximum power, regardless of engine rpm, it does present some limitations when it comes to performance camshafts. With such a wide range of valve timing movement, there is very little piston to valve clearance, which limits you to small cam profiles with little overlap.



Note: Fits L83 and L86 engine with aftermarket camshafts.
