  • Stress relieved, shot-peened, and 100% magnafluxed
  • Fully profiled knife-edged counterweights on the billet forgings
Piston Features:
  • Forged from 2618 alloy for maximum high temperature strength and fatigue resistance
  • "Contour forgings" provide the optimum balance between strength and weight with no grain-interrupting internal milling
