Spring Height Micrometer 1.400" to 1.800"

This is by far the quickest, easiest and most accurate way to measure valve spring installed height. You install our Height Mic just like you would a valve spring, then expand the tool until it has seated the valve, locks and retainer. This simulated seat pressure allows ultra precise readings. The tool is then read like a micrometer and is accurate to .001". The short model is for 4 and 6 cylinder engines, while the taller version covers most V8s.
