Hemi Phaser Hyd. Roller Cam 5.7/6.4L

The Hemi Phaser Hyd. Roller Cam 5.7/6.4L from COMP CAMS is a high-performance hydraulic roller camshaft engineered for Mopar Gen III Hemi engines seeking increased valve lift and extended duration for enhanced combustion efficiency. This camshaft is designed for enthusiasts and professional builders who demand improved breathing characteristics, greater power output, and reliable operation across a broad RPM range from 1800 to 6800. The hydraulic roller design eliminates valve lash adjustments while delivering consistent performance in street and mild performance applications.

This camshaft delivers intake valve lift of 0.612 inches and exhaust valve lift of 0.605 inches, with intake duration of 266 degrees and exhaust duration of 279 degrees—specifications that optimize cylinder filling and scavenging for superior volumetric efficiency. The 114-degree lobe separation angle (LSA) balances overlap and idle quality while promoting mid-range torque development. The hydraulic roller follower design reduces friction and wear compared to solid lifters, enabling cooler operation and extended service life. COMP CAMS' precision manufacturing ensures tight tolerances and consistent lobe profiles across all firing positions.

The Hemi Phaser Hyd. Roller Cam 5.7/6.4L is compatible with Mopar Gen III Hemi platforms, including 5.7L and 6.4L displacement variants found in Dodge, Jeep, and Chrysler performance vehicles. Installation requires proper valve train geometry verification and may necessitate supporting components such as pushrods, rocker arms, and valve springs to accommodate the increased lift specifications. Engine builders and tuners should verify cam timing and clearances during installation to ensure optimal performance and reliability in their specific application.
