Eagle Ford 429/460 Forged Crankshaft 4.500in Stroke

If you're building a high-performance Ford 429 or 460 engine, a strong crankshaft is the foundation of your build. This Eagle forged 4340 steel crankshaft is designed to handle serious power, featuring a 4.500-inch stroke for increased displacement and internal balance for smoother operation. It's built to be the core of a powerful engine that can take a beating.

Eagle starts with a non-twist forging of 4340 steel, known for its excellent strength and durability. They've added .125-inch fillet radii to the journals, which significantly boosts strength where it matters most, but this means you'll need chamfered or narrowed bearings to fit correctly. The crankshaft also receives a nitride surface treatment and a micropolish finish. This combination helps improve wear resistance and ensures proper oil flow, crucial for longevity under high stress.

This crankshaft is intended for demanding applications where reliability and performance are paramount. It's a well-built component that forms the backbone of a powerful engine build. Make sure to consult your engine builder or a trusted mechanic for specific installation requirements, especially regarding bearing selection and balancing procedures.
