COMP Cams Phaser Limiter Blocks

COMP Cams phaser limiter blocks are designed for Chrysler Hemi 5.7L, 6.1L, and 6.4L V8 engines equipped with cam phasers. These replacement blocks are used to help limit maximum cam phasing to 14 crankshaft degrees (7 camshaft degrees), helping provide the piston-to-valve clearance needed when running larger aftermarket camshafts. By reducing phaser travel, they help support more aggressive cam profiles for improved upper-RPM performance while maintaining strong low-end and mid-range power. These are the limiter blocks only--not a complete limiter or lock kit.
