COMP Cams 4925CPG Cam Degreeing Tool for GM and Ford Engines

The COMP Cams 4925CPG is a precision camshaft degreeing tool designed specifically for GM (0.842 inch diameter) and Ford (0.875 inch diameter) lifter bores. This innovative tool slides directly into the lifter bore and rides on top of the camshaft to accurately measure lobe lift and base circle runout when used with a dial indicator (sold separately).

Key Features:

• Built-in O-ring holds the tool firmly in the lifter bore for accurate measurements
• Reads cam lift to 0.001 inch precision with 1 inch travel dial indicator (not included)
• Includes two interchangeable followers: one for solid or hydraulic flat tappet cams and one for roller cams
• Double-ended design for versatility
• Compatible with GM 0.842 inch and Ford 0.875 inch diameter lifter bores

This cam checking tool is an essential instrument for engine builders and performance enthusiasts who need to verify camshaft specifications during installation or inspection. The tool eliminates guesswork by providing precise measurements of lobe lift and detecting any base circle runout issues that could affect engine performance.
