Eagle "ESP" 4340 Steel
Crankshafts
Mitsubishi 4G63
ESP Forged 4340 Steel Crankshafts feature exceptional strength and
unsurpassed quality at a reasonable price. Our cranks are forged in a
non-twist forging and undergo a multi-stage heat treatment process as
well as stress relieving, shot peening, and nitriding. They are
magnafluxed and sonic tested to insure quality. We micropolish each
journal to a 3 or better R.A. A 0.125 radius is used to increase
strength, so chamfered bearings must be used. The perfect choice for
engines up to 1500 HP!
