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. Includes 58 tooth reluctor and long snout for dry-sump oiling system.
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 0.125†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 .125†radius is used to increase strength, so chamfered bearings must be used. All use a Ford rod journal width regardless of journal diameter.
