Eagle Chrysler 360 4.125in Stroke 2.100in Rod Journals Forged 4340 Steel Crankshaft

This is the Eagle forged 4340 steel crankshaft specifically for Chrysler 360 engines. It features a 4.125-inch stroke and 2.100-inch rod journals, making it a robust choice for performance builds or heavy-duty applications where reliability is key. The non-twist forging process ensures that the crankshaft maintains its integrity under significant stress.

Built from 4340 steel, this crankshaft is designed for strength. The .125-inch fillet radii at the journals are chamfered, which requires the use of narrowed bearings but significantly boosts the crankshaft's resistance to cracking. Furthermore, the surface is nitrided and then micropolished. Nitriding hardens the surface to resist wear, while micropolishing creates an exceptionally smooth finish for reduced friction and improved oil flow, crucial for longevity in high-performance engines.

When installing this crankshaft, remember that the chamfered fillet radii mean you'll need to use specific narrowed bearings. This level of detail in the design points to its intended use in demanding applications where every component needs to perform reliably under pressure. It's a well-built foundation for a powerful engine build.
