Valve Spring Micrometer 1.600 - 2.200

The Valve Spring Micrometer 1.600 - 2.200 by COMP CAMS is an essential precision measurement tool for engine builders, performance mechanics, and serious automotive enthusiasts undertaking high-revving engine builds. This specialized micrometer allows you to measure valve spring free length and installed height with extreme accuracy—a critical step often overlooked by DIY builders but absolutely mandatory when assembling race engines or performance-modified heads. Proper valve spring measurement directly impacts camshaft profile effectiveness, valve timing stability, and overall engine reliability at elevated RPM.

This precision instrument features a measurement range of 1.600 to 2.200 inches, making it ideal for both single and dual-spring valvetrain configurations commonly found in modern performance and racing engines. The micrometer's design delivers repeatability and accuracy necessary for verifying that springs meet OEM or aftermarket specifications before installation. 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 engineered this tool to eliminate guesswork and ensure your valvetrain operates exactly as intended, whether you're building a street machine or competition engine.

Professional engine shops and serious builders rely on this micrometer when assembling any performance or high-RPM application where valvetrain precision cannot be compromised. It's equally valuable when diagnosing worn or damaged springs in existing builds or when matching replacement springs to exact OEM dimensions. Compact at 0.25 lbs and measuring 2.8 x 2.05 x 4.1 inches, it fits easily into any engine builder's toolkit and integrates seamlessly with other precision measurement instruments you're already using for cylinder head work, bore measurement, and deck height verification.
