Manley 5.7L Hemi 4340 4.050″ Stroke Crankshaft up to 2008, 32 teeth Reluctor Wheel, 1730 Bobweight, Total Weight 49-51lbs

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/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. 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.

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