Manley Performance
Manley Pro Series Forged Crankshaft 4.050in Stroke for Chrysler HEMI (5.7L / 6.1L / 6.4L) 191958NB
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits Chrysler Gen III Small Block HEMI engines including 5.7L, 6.1L, and 6.4L variants.
The Manley Performance Pro Series stroker crankshaft is engineered for high-output Gen III HEMI builds. This 4.050" stroke crankshaft allows for displacement increases up to 392 c.i. on 5.7L blocks and 426 c.i. on 6.1L and 6.4L engines. Manufactured from a premium 4340 steel forging, it undergoes a multi-step heat treatment and nitriding process for maximum surface hardness and fatigue resistance.
To optimize oil control and reduce windage, this crankshaft utilizes Small Block Chevy (SBC) small journal 2.000" crank pin diameters and widths, providing taller sidewalls on the rod journals. The counterweights are fully profiled for 6.125" connecting rods, and the snout features a dual keyed post to safely handle supercharger drive pulleys.
