Manley Chrysler 5.7L/6.1L Hemi 4340 Forged Crankshaft w/ 32 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 increases engine displacement, transforming a 5.7L HEMI into a 392 cubic inch engine or a 6.1L/6.4L into a 426 cubic inch engine. It incorporates small block Chevy small journal (2.000 inches) crank pin diameters and widths, providing taller side walls on the crankshaft rod journals for improved oil control and reduced windage. Counterweights are profiled for 6.125-inch connecting rods, enhancing balance and durability for high-performance applications.

This crankshaft is suitable for use in 2003-2008 Chrysler 5.7L and 6.1L/6.4L HEMI engines, serving as a robust upgrade for performance builds. It is designed as a direct bolt-in replacement for stock crankshafts, offering increased stroke and displacement for enhanced power output. Ideal for street, track, or custom engine builds, this component ensures reliable strength and improved engine efficiency. The kit includes the crankshaft and 32-tooth reluctor wheel, ready for installation in compatible HEMI engines.
