Eagle Chrysler 440 8 Bolt Rear Flange 4.625in Stroke 2.200in Rod Journals Forged Steel Crankshaft

This is a forged 4340 steel crankshaft from Eagle, specifically built for Chrysler 440 engines. It features an 8-bolt rear flange, a 4.625-inch stroke, and 2.200-inch rod journals. This crankshaft is designed for serious performance builds where strength and reliability are paramount.

Eagle starts with a non-twist forging of 4340 steel, which is known for its excellent strength-to-weight ratio. The fillet radii are .125 inches, which are chamfered or narrowed to work with specific bearings, enhancing overall strength. The surface of the crankshaft is nitrided for improved wear resistance and then micropolished to ensure smooth operation and optimal bearing life. These features combine to create a crankshaft that can handle the stresses of high-performance applications.

When installing this crankshaft, remember that the .125-inch fillet radii require chamfered or narrowed bearings. It's always best to consult the manufacturer's installation guide for specific details and recommended bearing clearances to ensure proper fitment and long-term durability.
