    4340 Non-Twist Forging

    Manley builds one of the best crankshafts available for our high performance world! Many engine building superstars rely on Manley forgings to throw down the horsepower numbers we demand, pass after pass. Manley starts with a 4340 steel non-twist forging that undergoes an extensive heat treating and stress relieving process. After that, it is shot peened, nitrided and 100% magnafluxed to ensure complete structural integrity was maintained throughout the forging process for durability and longevity.



    Features:
  • Internal balance, 2-piece rear seal applications
  • Lightweight design
  • 2.100'' Rod Journal diameter
  • Gun drilled rod journals (except p/n 660-190310, two center rod journals are not drilled)
  • Manufactured from 4340 non-twist forgings
  • Heat treated, stress relieved, shot peened and 100% magnafluxed
  • Micro polished large radius journals
