If you're building a Ford 351W for serious performance, this Eagle Competition Rotating Assembly is a solid foundation. It's designed to handle the demands of racing, including applications using nitrous or forced induction. This assembly gives you the core components needed to rebuild or upgrade your engine's rotating assembly with well-built parts.

At the heart of this kit is a 4.170-inch forged 4340 steel crankshaft, chosen for its strength and durability under high stress. Paired with this are 6.250-inch H-beam connecting rods, which are known for their robust design. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in high-performance builds. The pistons are forged 4032 aluminum from Mahle, featuring a -6.6cc flat top design with a 4.125-inch bore. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific engine build. To complete the assembly, King XP rod and main bearings are included, offering good performance and wear resistance for demanding use.

This rotating assembly is a significant step up from stock components, providing the strength and precision needed for a high-output engine. Remember that this assembly is not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder or refer to manufacturer instructions for proper installation and balancing procedures.
