Pushrod Length Checkers are crafted from a steel alloy with black oxide coating for years of accurate measurements.
Having the correct pushrods in your engine is a critical factor in proper rocker arm geometry, and this is the best tool to measure pushrod length (it reads like a micrometer).
Individual Length Checker Adjustable Range: 6.800" to 7.800"
Simply screws and unscrews by hand using the lines as pictured for measurement. Each full turn is .050"
This .050" full turn design is as of 3/1/18. Our previous version was .035" per turn. So if you purchased one previous to that date it is .035" per turn.
