Chry Hemi Roller Cam Button .715in Length

The COMP CAMS Chrysler Hemi Roller Cam Button in 0.715-inch length is a precision valve train component engineered for high-performance and stock Hemi engine builds. This roller cam button serves as a critical interface between your camshaft and rocker arm assembly, designed to reduce friction and wear on your cam lobe during aggressive driving or racing conditions. Whether you're rebuilding a 5.7L, 6.1L, or 6.4L Hemi engine, this OEM-specification component ensures proper valvetrain geometry and durability under sustained boost or high RPM operation.

COMP CAMS roller cam buttons feature hardened steel construction with precision-ground rolling surfaces that minimize contact stress compared to traditional flat buttons. The 0.715-inch length specification is critical for maintaining correct rocker arm geometry and push rod clearance in Hemi heads—any deviation can cause valvetrain bind, excessive lash, or premature lobe wear. The roller design actively reduces friction losses during the intake and exhaust events, preserving crank horsepower while extending component lifespan under sustained power delivery or track use.

Mechanics and engine builders restoring or upgrading Hemi platforms should source OEM-equivalent roller cam buttons when performing top-end work, valve spring upgrades, or performance cam swaps. The 0.715-inch dimension is specific to Chrysler Hemi applications and must match your rocker arm design to ensure proper preload and valvetrain clearance. Installation requires careful measurement during assembly to verify correct geometry before final torqueing of rocker pedestals.
