Eagle Pontiac 400 Forged Steel Crankshaft, 4.2500in Stroke

Eagle is well-known for building strong rotating assemblies for performance engines. This forged 4340 steel crankshaft is designed for the Pontiac 400 engine and features a 4.250-inch stroke, giving you more displacement for increased power potential. It's built with a non-twist forging process and .125-inch fillet radii, which add significant strength to the crank, especially around the journals.

To further enhance its durability, this crankshaft has a nitrided surface treatment and is micropolished. The nitriding hardens the surface, making it more resistant to wear, while the micropolishing ensures a smooth finish for optimal bearing performance. Because of the .125-inch fillet radii, you'll need to use chamfered or narrowed bearings when installing this crank. This is a solid choice if you're building a high-performance Pontiac 400 and need a robust crankshaft that can handle serious power.
