The crankshafts are cross-drilled and have chamfered oil holes for improved oiling. The journals are precision-ground and micro-polished to under 5 RA. A 88mm and 94mm version are available for stock and stroker motors. When buying Eagle you are getting top quality parts that will withstand almost anything you can throw at it!
