Master Pushrod Checking Kit - 6.125-11.50 Range

The Master Pushrod Checking Kit from COMP CAMS is an essential precision tool for engine builders, performance mechanics, and serious automotive enthusiasts who demand accuracy during small-block and big-block Chevy engine assembly. This kit addresses one of the most critical yet commonly overlooked variables in valvetrain geometry: pushrod length selection.

Incorrect pushrod length compromises rocker arm geometry, reduces valve lift, creates excessive valve lash, and accelerates wear on costly camshaft and lifter components—problems that only reveal themselves after engine startup or full load testing. This checking kit covers the critical 6.125 to 11.50 inch pushrod range, accommodating nearly every street and performance engine combination using traditional solid or hydraulic roller lifter designs.

The kit operates on the principle of direct measurement, allowing you to establish baseline pushrod geometry, measure actual valve cover heights, rocker arm positions, and stack-up tolerances, then calculate the exact pushrod length required for optimal rocker arm geometry. This tool is indispensable for engine builders working with a variety of engine configurations.
