ZRP bring overkill into the production of performance crankshafts by using 4340 instead of EN40; In the world of high-performance crankshafts, nickel-chrome-moly alloy SAE-4340 (AMS-6414) has been a favourite in both forged & billets applications. It is used because of its very high strength & fatigue properties, couples with good ductility and impact resistance at high strength.
