Eagle Chevrolet 350 3.500in Stroke Forged 4340 Featherweight Steel Crankshaft

This product is the Eagle Chevrolet 350 3.500in Stroke Forged 4340 Featherweight Steel Crankshaft, part number 4350350057FW. It's a forged 4340 steel crankshaft designed with a 3.500-inch stroke specifically for Chevrolet 305 and 350 engines.

Eagle has engineered this crankshaft with a non-twist forging process and a lightweight counterweight design. The goal here is to significantly reduce rotating weight, which is crucial for performance in restricted-class competition applications. To further enhance its strength, it features .125-inch fillet radii, meaning you'll need to use chamfered or narrowed bearings. The crankshaft also has a nitrided surface and is micropolished for improved durability and smooth operation. For balancing purposes, you will need to use lightweight rods and pistons with this crankshaft.

This crankshaft is intended for competition use where reducing mass is a key factor in performance. Always refer to the manufacturer's installation instructions for specific requirements regarding bearing selection and balancing procedures.
