Mills Specialty Products invented and introduced the Cam-Check in 1978. Extremely useful when degreeing in a cam shaft, many engine builders and racers have found this tool invaluable.

The Cam-Check measures cam lobe lift quickly and accurately. A simulated flat or radiused lifter, contained in a sleeve that also holds a dial indicator, rides on the cam lobe. The entire tool slips into the lifter bore where an o-ring on the sleeve retains the tool securely in place.
