Manley Chrysler 5.7L/6.1L Hemi 4.050in Stroke 4340 Forged Crankshaft w/ 58 Tooth Reluctor Wheel

The Manley Performance PRO SERIES stroker crankshaft is a high-performance component designed for the Gen III small block HEMI engine. Crafted from a premium 4340 steel forging, this crankshaft features a 4.050-inch stroke that transforms a 5.7L engine into a 392 cubic inch displacement and a 6.1L or 6.4L engine into a 426 cubic inch displacement. It incorporates small block Chevy small journal (2.000-inch) crank pin diameters and widths, providing taller side walls on the crankshaft rod journals for improved oil control and reduced windage. The counterweights are profiled for 6.125-inch connecting rods, enhancing balance and performance. This crankshaft offers durability, precision engineering, and increased power potential for performance builds.

Designed for use in Gen III small block HEMI engines, this crankshaft is suitable for 5.7L, 6.1L, and 6.4L applications. It is a direct replacement or upgrade for stock crankshafts in compatible Chrysler HEMI engines, ideal for performance enthusiasts seeking increased displacement and torque. Installation involves standard bolt-on procedures, and the crankshaft includes a 58-tooth reluctor wheel for proper engine timing. Suitable for street, track, or high-performance applications, this crankshaft provides a reliable foundation for building more powerful HEMI engines.
