The Eagle featherweight forged 4340 steel crankshaft for Chevrolet 305/350 applications features a non-twist forging and lightweight counterweight design to reduce rotating mass. It uses .125" fillet radiuses for improved strength, a nitrided surface and micropolished journals. Intended for restricted-class competition use, this crank requires properly matched lightweight rods and pistons for correct balancing.
