Eagle forged 4340 steel crankshaft for Ford 429/460 engines, 4.140" stroke with 2.200" rod journals and internal balance. The non-twist forging and .125" fillet radiuses provide superior strength and require chamfered or narrowed bearings. Nitrided surface treatment and micropolished journals improve wear resistance. Intended for demanding, high-load engine applications requiring a strong forged crank.
