Eagle forged 4340 steel crankshaft for Chrysler B‑B series engines, 3.750" stroke. The non-twist forging and .125" fillet radiuses provide superior strength and require chamfered or narrowed bearings. Nitrided surfaces and micropolished journals enhance wear resistance and longevity. This crank is intended for demanding, high-load applications where a durable forged crankshaft is required.
