COMP Cams Dial Bore Gauge Combo measures rod bores, main bearings and cylinder bores. Setting the bore gauge to zero with a master or micrometer allows you to see the difference in the bore that you are measuring so a precise measurement can be performed. These indicators can automatically zero in at any position and convert inch/metric with the push of a button.
