Manley Performance “PRO SERIES” stroker package is designed for the 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.
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. The counterweights are profiled for 6.125" length connecting rods.
All crankshafts are shipped with either a 32 tooth or 58 tooth reluctor wheel installed.
