Eagle Standard Forged Crankshaft 4340 Chromoly Steel

Eagle is well-known for building strong rotating assemblies for performance engines. This standard forged crankshaft is a prime example, crafted from 4340 chromoly steel for serious power builds. It's designed to handle the stress of high RPMs and significant horsepower, making it a solid foundation for a performance engine rebuild.

What sets this crankshaft apart is its non-twist forging and center counterweights. These features add stability when the engine is spinning fast, which is crucial for preventing issues in high-power applications. The fillet radii are 125 inches, which is a notable strength increase, but it means you'll need chamfered or narrowed bearings. The surface is also nitrided and micropolished, further enhancing its durability and smooth operation. This level of attention to detail ensures the crankshaft can withstand the rigors of demanding use.

This crankshaft is intended for the Ford 4.6L Modular V8 engine. When building a high-performance engine, the crankshaft is a critical component, and this Eagle unit offers the strength and stability needed for builds pushing the limits. Remember that due to the 125" fillet radii, you will need to use chamfered or narrowed bearings to ensure proper fitment and function.
