Eagle Ford 351W 4.170in Crank 6.250in H-Beam -6.6cc Flat Top 4.155in Pistons Rotating Assembly

Starting with a 4.170-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance, especially if you're planning on using nitrous or forced induction. The crankshaft is paired with 6.250-inch H-beam connecting rods, which are known for their strength and reliability under high stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their durability and ability to hold tight under extreme loads.

The pistons included are forged 4032 aluminum from Mahle, featuring a -6.6cc flat top design and a 4.155-inch bore size. These pistons are designed to work with the included plasma-moly file-fit piston rings, allowing for precise gap setting to match your specific engine build and application. To complete the assembly, King XP rod and main bearings are supplied, offering excellent wear resistance and performance for the critical rotating components.

This is a well-built rotating assembly intended for demanding applications where strength and precision are paramount. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a solid foundation for a high-performance Ford 351W engine build.
