Eagle Balanced Rotating Assembly Kit

This Eagle Street & Strip Balanced Rotating Assembly Kit gives you the core components to rebuild or upgrade the bottom end of your Ford 351W engine. It’s designed for street vehicles running on pump gas and naturally aspirated setups, offering a well-built foundation for your build. You'll receive a balanced 4.000-inch cast crankshaft, a set of 6.200-inch I-beam connecting rods secured with 3/8-inch ARP 8740 bolts, and hypereutectic KB pistons with a -6.5cc flat top design in a 4.030-inch bore size. The kit also includes plasma-moly file-fit rings, King rod and main bearings, a damper, and a 157-tooth flexplate, providing a comprehensive package to get your engine rotating.

The components in this kit are selected for reliable street performance. The cast crankshaft is balanced to ensure smooth operation, while the I-beam connecting rods with ARP bolts offer solid strength for typical street use. The KB hypereutectic pistons are a popular choice for their durability on pump gas, and the plasma-moly file-fit rings allow for proper sealing in your cylinders. King bearings are known for their consistent performance, and the included damper helps manage torsional vibrations. This assembly is a popular option for those looking to refresh or enhance their 351W's short block.

It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's specific installation instructions for proper assembly and torque specifications, as well as any recommended break-in procedures for the bearings and rings.
