INSTALLATION INSTRUCTIONS
Note: These instructions give a very basic overview of what is required to install the COMP Cams
® GM Cam
Phaser Limiter Kit. They in NO WAY replace the VERY specific factory instructions for removing and replacing
the camshaft. Failure to follow the specific factory recommended instructions for removal and replacement of the
camshaft during the installation of the cam phaser limiter can lead to an incorrectly timed camshaft and resulting
engine damage.
WARNING!!!!
Extreme care must be taken when handling the cam phaser. In particular, the thin metal sensor
trigger wheel that is attached to the front of the cam phaser is only held on by a light friction fit
once the cam bolt is removed. Do NOT handle the cam phaser by this trigger wheel, as it pulls off
it’s installation pins very easily if care is not taken. A safety bolt is provided in the kit that will
hold this trigger wheel in place while handling. Remember to install this safety bolt while
handling the cam phaser. If the trigger wheel comes off the cam phaser, the coil spring on the
front of the gear will unwind and the cam phaser will be ruined, requiring you to purchase
another.
VERIFY CAM PHASER!!!!
GM designed 62 crank degrees of total cam phaser movement for the L92, 2007-2008 LS1 and
2014 LT1/L83 model year engines. For 2009 and newer engines, this was mechanically reduced
to 52 degrees. Due to the fact that the factory often times makes running changes in their
production line, regardless of what year engine you may have, it is always a good idea to verify
which cam phaser you have installed in the engine. See the pictures below and compare the
measurements from your cam phaser to them:
2007-2008 L92 cam phasers have a
.935 in. chamber width (62 crank deg.) 2009-current cam phasers have a .815
in. chamber width (52 crank deg.)
