No rod should be reconditioned or pins fit without precise gaging. The only way to know the bore size is to measure the bore, and there is no better way to measure rod bores than with Sunnen's AG-300 and AG-400 Precision Gages. The AG-300 and AG-400 are the only gages specifically designed for both clearance and press type pin fits and the journal end of connecting rods.
Both gages come complete with setting fixture, calibrator rings, medium and large extension point sets, accessory case, mounting bracket and instructions.
