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

Starting with a forged 4340 steel crankshaft featuring a 4.170-inch stroke, this Eagle rotating assembly is built for serious performance applications, including those using nitrous or forced induction. The H-beam connecting rods measure 6.250 inches and come equipped with 7/16-inch ARP 8740 bolts, offering a strong link between the crank and pistons. This assembly is designed to handle the stresses of high-output engines.

The included Mahle pistons are forged from 4032 aluminum and feature a flat-top design with a -6.6cc volume, which helps achieve a desired compression ratio when paired with your cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's bore and intended use. King XP rod and main bearings are also part of this balanced assembly, providing reliable lubrication and reduced friction for the rotating components.

This balanced assembly is ready to be installed into your Ford 351W engine. Please note that this part is not CARB approved and cannot be shipped to California. It is important to consult the manufacturer's installation instructions for proper assembly and break-in procedures to ensure optimal performance and longevity.
