Cam Phaser Limiter Kit GM LT4

The Cam Phaser Limiter Kit GM LT4 by COMP CAMS is designed for serious LS and LT engine builders who require precise cam timing control and reliability in high-RPM conditions. This kit is particularly beneficial for those engaged in forced-induction applications or extended track use, where maintaining engine integrity is crucial.

The kit provides mechanical constraints on cam phaser travel, effectively preventing phaser rattle and unwanted advance. By restricting maximum phaser travel, it ensures predictable valve overlap and protects against internal damage that can occur from excessive phasing. The hardware is precision-machined to fit within OEM phaser geometry, requiring no permanent modifications to the engine block or cylinder heads.

This limiter kit is essential for LT4 owners who have upgraded fuel systems, added forced induction, or installed aggressive cam profiles that exceed factory design parameters. Mechanics experienced with engine modifications will find the installation straightforward, making it a valuable addition to any performance-oriented LT4 setup.
