About this part

Product Details

Starting with a forged 4340 steel crankshaft with a 4.000-inch stroke is key to building a robust Ford 351W engine. This rotating assembly from Eagle is designed for serious performance, including applications using nitrous or forced induction. It brings together all the critical components you need to get your engine's bottom end rebuilt or upgraded.

The 6.250-inch H-beam connecting rods are strong and reliable, featuring 7/16-inch ARP 8740 bolts to ensure they stay securely fastened under high stress. Paired with these are the 4.125-inch, flat-top pistons from Mahle, made from 4032 forged aluminum. These pistons have a -6.6cc dish, which is important for setting your compression ratio. The assembly also includes plasma-moly file-fit piston rings, allowing for precise ring gap adjustment to match your specific build. For the main and rod bearings, Eagle has included King XP bearings, known for their durability and performance.

This is a comprehensive rotating assembly, meaning you get the crankshaft, connecting rods, pistons, rings, and bearings all in one package. This simplifies the purchasing process and ensures that the core components are designed to work together. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
