A bore gauge with more reach Goodson's 90-degree bore gauge is designed to measure cam bores, main bores and other hard-to-reach areas directly. The 90-degree bore gauge eliminates the need to pass through other bores to measure inboard journals. It provides a .050" travel in .0001" increments, and has a capacity of 2" to 6". The set includes three spacers, 11 probes and the case.
