About this part

Product Details

If you're building a high-performance Chrysler Hemi engine, this Eagle forged 4340 steel crankshaft is a solid foundation. It's designed for the 5.7L, 6.1L, and 6.4L Hemi platforms, offering a 4.050-inch stroke to increase displacement and power potential. This crankshaft is built to handle demanding applications, making it a key component for serious engine builds.

Eagle starts with a non-twist forged 4340 steel billet, which is known for its strength and reliability under stress. The fillet radii are increased to .125 inches and chamfered, requiring narrowed bearings, but this design significantly boosts strength, preventing cracks from forming in high-stress areas. The crankshaft also features a nitrided surface treatment for improved wear resistance and a micropolished finish on the journals for smooth operation and reduced friction. This crankshaft comes equipped with a 58-tooth reluctor wheel, essential for the engine's computer to accurately read crankshaft position.

When installing this crankshaft, remember that the .125-inch fillet radii and narrowed bearing requirement are important considerations. It's crucial to use the correct bearings and ensure proper clearances for optimal performance and longevity. This crankshaft is a substantial upgrade for anyone looking to push the limits of their Hemi engine.
