COMP Cams® Valve Spring Height Micrometers are now black anodized for ease of reading and superior corrosion resistance.

COMP Cams® Valve Spring Height Micrometers are the quickest, easiest, most accurate way to measure valve spring installed height. Now, these tools are even easier to read with white markings that stand out on a black anodized finish. This new finishing process also helps protect against stains and corrosion. Simply install any of these micrometers just like a valve spring, and then expand the tool until it fully seats the valve, locks and retainer. The tools are read like a micrometer and are accurate to .001? because the simulated seat pressure creates ultra precise measurements. The shortest model is for 4 and 6 cylinder engines, while the taller versions cover most V8 applications. In addition, COMP Cams® now offers a model specifically designed for Beehive™ Valve Springs.
