Eagle Standard Forged 4340 Chromoly Steel

Forged from 4340 chromoly steel, this Eagle crankshaft features center counterweights designed for improved stability when your engine is running at high RPMs and under high power loads. The non-twist forging process ensures a strong, reliable foundation for your engine build. This crankshaft has 125-inch fillet radii, which are chamfered for superior strength, meaning you'll need chamfered or narrowed bearings to go with it. The surface is nitrided and then micropolished for an improved finish.

This crankshaft is built for demanding applications and is a solid option for those rebuilding or modifying their Ford 4.6L Modular V8 engine. It offers a 3.554-inch stroke, providing a good balance for performance builds. This part fits a wide range of Ford vehicles, including models like the Crown Victoria, Expedition, and F-150, among others.

When installing this crankshaft, remember that the nitrided surface and micropolished finish are key to its longevity and performance. Always refer to the manufacturer's installation instructions for specific details regarding bearing selection and assembly procedures to ensure proper function and durability.
