Valve Spring Micrometer 1.600 - 2.200

The Valve Spring Micrometer 1.600 - 2.200 by COMP CAMS is a precision measurement tool designed for engine builders, performance mechanics, and automotive enthusiasts engaged in high-revving engine builds. This specialized micrometer is essential for accurately measuring valve spring free length and installed height, which are critical factors in ensuring optimal engine performance. Proper measurement is often overlooked by DIY builders but is crucial for assembling race engines or performance-modified heads.

This precision instrument features a measurement range of 1.600 to 2.200 inches, making it suitable for both single and dual-spring valvetrain configurations commonly found in modern performance and racing engines. The micrometer is engineered to deliver the repeatability and accuracy necessary for verifying that springs meet OEM or aftermarket specifications before installation. Accurate valve spring measurement directly impacts camshaft profile effectiveness, valve timing stability, and overall engine reliability at elevated RPM.

Professional engine shops and serious builders rely on this micrometer when assembling any performance or high-RPM application. When installed height deviates from specification, spring preload changes dramatically—too little preload risks valve float at peak RPM, while excessive preload accelerates wear and reduces engine longevity. COMP CAMS designed this tool to eliminate guesswork and ensure your valvetrain operates exactly as intended, whether you're building a street machine or a competition engine.
