Comp Cams Lobe Indicator Tool

This innovative tool actually slides down into the lifter bore and rides on top
of the camshaft in order to measure lobe lift and base circle runout. Each
tool includes two followers: one for flat tappet cams and one for rollers. Two
models are available and each is double ended.
• Built-in o-ring holds tool firmly in the lifter bore while 1" travel dial indicator
(not included) reads cam lift to .001"
