Eagle Chrysler RB 4340 Crank 4.25 Stroke 2.2 Rod Pin 8 Bolt Flange

This Eagle crankshaft is forged from 4340 steel, offering a robust foundation for your Chrysler RB engine build. You get a crankshaft with a 4.250-inch stroke and 2.200-inch rod journals, designed for the 8-bolt rear flange configuration common in many performance applications.

Eagle uses a non-twist forging process for this crank, which helps ensure its strength and straightness under stress. The .125-inch fillet radii are chamfered, meaning you'll need to use chamfered or narrowed bearings to properly seat this crankshaft. It's also nitrided and micropolished, surface treatments that significantly improve wear resistance and durability, making it well-suited for high-performance engines where reliability is key.

When building a serious engine, the crankshaft is a critical component. This Eagle unit is built to handle the demands of performance applications, providing a solid, well-built piece for your project.
