Eagle forged 4340 steel crankshaft for Chevrolet 305/350 with a 3.875" stroke and a one-piece rear seal configuration. The non-twist forging and .125" fillet radiuses increase structural integrity and call for chamfered or narrowed bearings. Nitrided and micropolished journal surfaces help resist wear, making this crank suitable where a sealed rear installation and durability are priorities.
