Forged 4340 Steel Crankshafts
Cast Steel Crankshafts
Reliable, affordable cast steel crankshafts are inspected for dimensional accuracy.
Unsurpassed quality and exceptional strength at an affordable price. Cranks begin as non-twist 4340 forgings which are ground, cross-drilled, stress-relieved, shot-peened, micro-polished and nitrided during the manufacturing process. Rod journals are indexed for correct stroke, and the crankshaft is inspected for proper dimensions. It is then micro-polished, x-rayed, magna- fluxed and sonic tested prior to shipping.
