    No rod should be reconditioned or pins fit without precise gaging. The only way to know the size is to measure the hole. Sunnen's AG-300 and AG-400 Precision Gages are designed for pin fitting and rod reconditioning. 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.
