Nitto EN40B Billet Steel crankshafts are manufactured from high quality true billet round bar stock. Most other aftermarket crankshafts are manufactured using cast forged material, which is a much cheaper manufacturing process and hence carry a cheaper price tag, but their performance, strength and horsepower capabilities are significantly compromised compared to that of a true billet crankshaft. An engine with a EN40B billet steel crankshaft will rev faster and cleaner due to the different harmonics produced from the high grade material.

All of our EN40B cranks are:
  • EN40B Billet Round Bar Stock

  • Grade Tested (X-ray - Sonic)

  • Quenched and Heat Treated

  • Fully Counter Weighted

  • Nitrided

  • Balanced

  • Knife Edged (where applicable)

  • 100% CNC Profiled

  • 100% CNC Drilled and Tapped
