Manley Chrysler 5.7L/6.1L Hemi 4.080in Stroke 4340 Forged Crankshaft w/ 32 Tooth Reluctor Wheel

This is the Manley "Pro Series" 4340 forged crankshaft, designed for Chrysler 5.7L and 6.1L Hemi engines. If you're looking to significantly increase your engine's displacement and unlock more power, this crankshaft is a solid foundation for a performance build. It features a 4.080-inch stroke, which can transform a 5.7L Hemi into a 392 cubic inch engine, or a 6.1L/6.4L Hemi into a 426 cubic inch powerhouse.

Manley builds these crankshafts from strong 4340 alloy steel and subjects them to a multi-step heat treatment and nitriding process, which greatly enhances their strength and ensures they last. They've also worked to reduce weight by gun drilling the mains and lightening the rod journals, while profiling the counterweights for precise balance. The journals are micro-polished with large radii to cut down on friction, helping your engine perform at its best. Before they leave the factory, each crankshaft is stress relieved, shot peened, and 100% magnafluxed to meet Manley's strict quality standards, so you know you're getting a well-built part.

This crankshaft comes with a 32-tooth reluctor wheel, which is important for your engine's computer to accurately read engine speed. When building a high-performance Hemi, a strong, well-balanced crankshaft like this is crucial for reliability and power output. Be sure to consult your engine builder or a trusted mechanic for specific installation requirements and supporting modifications needed for your build.
