Manley Performance is proud to introduce our "PRO SERIES" stroker crankshaft 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 6.1L 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. The counterweights are profiled for 6.125" length connecting rods.
