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.\nStroke: 4.050 in. - Rod Journal: 2.000 in. - Reluctor Wheel: 32 Tooth - Bobweight: 1730 grams\nThe stock timing crank gear may need to be chamfered to clear the larger radius on the snout of the crankshaft - All 2012 and earlier 58 tooth reluctor wheels have a tooth width of .170” - All reluctor wheels are attached with 4 fasteners.\n\u003cul\u003e\n  \u003cli\u003eMulti-step heat treatment process and nitrided for added strength to already strong forged 4340 material\u003c\/li\u003e\n  \u003cli\u003eMicro polished large radius journals (narrow rod bearings required)\u003c\/li\u003e\n  \u003cli\u003eGun drilled mains and lightened rod journals for weight reduction\u003c\/li\u003e\n  \u003cli\u003eStress relieved, shot-peened and 100% magnafluxed\u003c\/li\u003e\n  \u003cli\u003eDual keyed post for supercharger drive pulleys\u003c\/li\u003e\n  \u003cli\u003eCounterweights fully profiled\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUpgrade your HEMI engine with the Manley Performance PRO SERIES forged crankshaft designed specifically for Gen III small block HEMI engines. Crafted from premium 4340 steel forging, this crankshaft offers exceptional strength and durability for high-performance applications. Featuring a 4.050-inch stroke, it effectively increases engine displacement from 5.7L to 392 cubic inches or from 6.1L\/6.4L to 426 cubic inches, providing significant power gains. The crankshaft's small journal crank pin diameter of 2.000 inches ensures improved oil control and reduced windage, contributing to smoother engine operation and longevity. The profiled counterweights are optimized for 6.125-inch connecting rods, promoting balanced operation and reducing vibrations. The crankshaft also includes a 32-tooth reluctor wheel, essential for engine timing and sensor compatibility, and features a dual keyed post for supercharger drive pulleys. \u003c\/p\u003e\u003cp\u003eManufactured through a multi-step heat treatment process and nitrided for added strength, this forged component maintains integrity under demanding conditions. The micro-polished large radius journals require narrow rod bearings, enhancing oil film stability. Gun drilling of mains and lightening of rod journals reduce weight without sacrificing strength, improving overall engine responsiveness. Each crankshaft is stress relieved, shot-peened, and inspected with 100% magnaflux testing to ensure quality and reliability. Please note that the stock timing gear may require chamfering to clear the larger radius on the crank snout. Designed for enthusiasts seeking reliable power upgrades, the Manley HEMI crankshaft is a critical component for high-performance engine builds. \u003c\/p\u003e\u003cp\u003eNote: All reluctor wheels are attached with four fasteners and are compatible with 58-tooth reluctor systems from 2012 and earlier.
