Our ModMax forged 4340 Crankshafts for 4.6L engines are a must when adding horsepower to your Modular engine. These cranks feature strong 4340 forgings for high strength and durability. This model is a stock stroke 3.543" crank for a drop in installation for any 4.6 engine using stock dimension connecting rods. It has added material and additional computer designed center counterweights and is designed to be internally balanced. The rod and main journals feature full .125" racing radii so chamfering of both main and rod bearings may be required for fitment. These cranks have been used in 1000+ horsepower engines with no failures. NOTE: These cranks have 8 bolt flywheel flanges so you may need to purchase the correct flywheel or flexplate if your current engine has a 6 bolt crank.
