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 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.
- 4340 material forging
- Multi-step heat treatment process and Nitrided for added strength
- Stress relieved, shot-peened, and 100% magnafluxed
- Micro polished large .125" radius journals (narrowed rod bearings required)
- Dual keyed post for supercharger drive pulleys
- Gun drilled mains and lightened rod journals for weight reduction
