Manley Chrysler 5.7L/6.1L Hemi 4340 Forged Crankshaft w/ 32 Tooth Reluctor Wheel

Manley Performance is proud to introduce their "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 5.7L into a 392 c.i. engine and 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. All crankshafts are shipped with either a 32 tooth or 58 tooth reluctor wheel installed.

NOTE: All 2008 and earlier 5.7L and all 6.1L have a 32 tooth reluctor wheel. All 2009 and later 5.7L have a 58 tooth reluctor wheel.
