Manley Chrysler 5.7L/6.4L Hemi 4.050in Stroke 4340 Forged Crankshaft w/ 58 Tooth Reluctor Wheel - 191958

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.

When installing these crankshafts in a VVT engine, you also need to order a crankshaft gear spacer part number 42000 - All 2013 and later 58 tooth reluctor wheels have a tooth width of .130”, along with a dimple in the rear face of the wheel - All reluctor wheels are attached with 4 fasteners
