Manley Performance “PRO SERIES” stroker crankshaft designed for the Gen III small block HEMI engine. Manufactured from a premium 4340 steel forging, these cranks feature a 4.050” stroke which can turn your 5.7L into a 392 c.i. engine and your 6.1L/6.4L into a 426 c.i. engine. The Manley 4.050” stroke HEMI crankshaft features small block Chevy small journal (2.000") crank pin diameters and widths. This provides taller "side walls" on the crankshaft rod journals for better oil control and reduced windage. Counterweights are profiled for 6.125" connecting rods.
