Description

Eagle forged 4340 steel Cranks feature a non-twist forging, .125" fillet radiuses for superior strength so chamfered / narrowed bearings required, nitrided surface and micropolished. Intended for the most demanding applications.

Product Overview

Eagle Crankshafts feature exceptional strength and quality at a reasonable price. Eagle 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. Every journal is micropolished to a 3 or better R.A. On all journals, a 0.125Ã¢â‚¬Â radius is used to increase strength, so chamfered bearings must be used. The perfect choice for engines up to 1500HP! *4340 Steel Crankshafts* Eagle forged 4340 steel crankshafts are forged from SAE 4340 steel, feature a non-twist forging, multi-stage heat treat process, stress relieving, shot-peening, and nitriding for superior strength and reliability in the most demanding applications. Each journal is micropolished to a 3 r.a. or better. A .125Ã¢â‚¬Â radius is used to increase strength, so chamfered bearings must be used. All use a Ford rod journal width regardless of journal diameter. All are designed for internal balance. These are the perfect choice for applications up to 1500 hp. Eagle Forged 4340 Steel Crankshafts are also available in 'Lightweight' versions - Counterweights are knife-edged for reduced weight and less windage. Typical weight reduction is 5-6 lbs. *Cast Steel Crankshafts* Eagle cast steel crankshafts offer an excellent alternative to a factory cast crank.
