Manley Performance "PRO SERIES" crankshafts designed for the Ford 4.6L Modular engine. Manufactured from a premium 4340 steel forging, these cranks feature either the stock 3.543" stroke or an increased stroke of 3.750", turning your 4.6L into a 5.0L or larger depending on your bore.

4340 material forgings
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)
Lightened rod journals for weight reduction
Counterweights fully profiled

The stock timing crank gear may need to be chamfered to clear the larger radius on the snout of the crankshaft. These crankshafts are designed with an 8 bolt pattern flywheel. They can be used in place of 6 bolt pattern crankshafts when used along with an OEM or aftermarket 8 bolt flywheel. Manley crankshafts are not intended for use with highly boosted roots style cog belt superchargers
