Eagle Chrysler 360 4.250in Stroke 2.100in Rod Journals Forged 4340 Steel Crankshaft

If you're building a high-performance Chrysler 360 engine and need a crankshaft that can handle serious power, this forged 4340 steel unit from Eagle is a solid choice. It's designed to replace the stock crankshaft and is built for applications where reliability under extreme stress is paramount. This crankshaft features a 4.250-inch stroke, which is longer than stock, and 2.100-inch rod journals, allowing for larger piston combinations and increased displacement for more power.

Eagle starts with a non-twist forging of 4340 steel, a material known for its strength and durability, then treats it with a nitrided surface finish and micropolishing. This process helps resist wear and fatigue, crucial for a component that spins thousands of times per minute under heavy load. The fillet radii are .125 inches, which are designed for superior strength, but it means you'll need to use chamfered or narrowed bearings to ensure proper clearance. This level of detail in the design shows it's built for demanding performance builds.

When you're aiming for maximum output from your Chrysler 360, the crankshaft is the backbone of your engine. This Eagle crankshaft is a well-built component that provides the foundation for a powerful and reliable engine build. Make sure to consult your engine builder or a trusted mechanic regarding bearing selection and proper installation procedures to get the most out of this performance crankshaft.
