Eagle Ford 460 4.140in Stroke 2.200in Rod Journals Internal Balance Forged 4340 Steel Crankshaft

This Eagle crankshaft is built for the Ford 460 engine, featuring a 4.140-inch stroke and 2.200-inch rod journals. It's designed for internal balance, meaning it's balanced to work with specific harmonic balancers and flywheels, simplifying setup for many performance applications. This is a forged 4340 steel crankshaft, a material known for its exceptional strength and durability under high stress.

Eagle starts with a non-twist forging process for this crank, ensuring consistent material integrity throughout. The .125-inch fillet radii are chamfered, which is important because it means you'll need to use chamfered or narrowed bearings to ensure proper clearance and oil flow. The surface of the crankshaft is nitrided for increased hardness and wear resistance, then micropolished to a smooth finish. These features combine to make it well-suited for demanding engine builds where reliability and performance are critical.

When building a high-performance engine, the crankshaft is the backbone. This Eagle forged steel crank offers a solid foundation for your Ford 460 project. Remember to consult your engine builder or service manual for specific bearing recommendations and installation procedures, especially regarding the chamfered fillets.
