Cam Checker Tool

The PROFORM Cam Checker Tool is a precision camshaft checking fixture designed for engine builders, performance mechanics, and enthusiasts who need accurate valve lift and duration measurement during cam installation or verification. Whether you're installing a stock replacement camshaft, upgrading to a performance grind, or diagnosing valve train issues, this fixture eliminates guesswork by providing repeatable, reliable baseline data before your engine runs. It fits universal lifter bores across flat-tappet and hydraulic follower designs, making it an essential addition to any serious engine shop or home garage.

This cam checker features a 0.001-inch dial indicator for precision measurement, aluminum construction that resists wear while remaining lightweight and portable, and a design optimized for flat and hydraulic camshaft followers. The fixture clamps securely to your cylinder head, allowing you to rotate the crankshaft by hand or engine turning while the dial indicator reads actual valve lift in real time. The 0.001-inch resolution means you'll catch subtle timing variations, bent pushrods, or incorrect lobe geometry that could compromise engine performance or reliability. The aluminum body minimizes thermal expansion errors during measurement, and the universal design accommodates the majority of domestic and import overhead-valve engine architectures.

Performance-minded owners building stroker engines, street/strip combinations, or mild-to-wild crate motor swaps benefit most from having a cam checker on hand before final assembly. The fixture is equally valuable for troubleshooting valve train noise, verifying cam core shift after aggressive dyno sessions, or confirming that a used cam core meets advertised lift specifications. Its compact dimensions (4.9 x 2 x 10.65 inches) and modest 0.72-pound weight make storage and portability simple, while the included kit format means everything needed for flat and hydraulic lifter verification comes ready to use. This is the tool that separates data-driven engine building from assumption-based assembly.
