Eagle Ford 351W 4.170in Crank 2.750in Journal 6.250in I-Beam Rods 4.125in Pistons Rotating Assembly

Built around a 4.170-inch forged 4340 steel crankshaft, this rotating assembly from Eagle is designed for Ford 351W engines looking for serious performance, especially in naturally-aspirated racing applications. The crankshaft features 2.750-inch main journals, a common size for many Ford performance builds, ensuring good compatibility with a wide range of aftermarket and performance-oriented engine blocks. This is a well-built foundation for a powerful engine.

Complementing the robust crankshaft are 6.250-inch I-beam connecting rods, also forged from 4340 steel for exceptional strength and durability under high stress. These rods come equipped with 7/16-inch ARP 8740 bolts, known for their reliability and ability to maintain clamping force even in demanding conditions. The assembly includes forged 4032 aluminum flat-top pistons from Mahle, featuring a -6cc dish to help achieve a desired compression ratio, paired with plasma-moly file-fit piston rings. King XP rod and main bearings are also included, offering improved performance and wear resistance for critical rotating components.

This rotating assembly is a substantial upgrade for anyone rebuilding or building a performance Ford 351W engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures to ensure optimal performance and longevity.
