Manley Chrysler 5.7L Hemi Forged Crankshaft - 4.050in Stroke
Sale price
$1,476.70
Regular price $1,358.99Pickup currently unavailable
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.
- Multi-step heat treatment process and nitrided for added strength to already strong forged 4340 material
- Micro polished large radius journals (narrow rod bearings required)
- Gun drilled mains and lightened rod journals for weight reduction
- Stress relieved, shot-peened and 100% magnafluxed
- Dual keyed post for supercharger drive pulleys
- Counterweights fully profiled
