Eagle Chevy 454 1Pc 4.250in Counterwght Crank 6.385in H-Beam 43cc 4.350in Pistons Rotating Assembly

If you're building a high-performance Chevy 454 for serious competition, like drag racing, heavy nitrous use, or high boost applications, a strong rotating assembly is the heart of your engine. This Eagle Heavy Duty Rotating Assembly is designed to handle those extreme demands, giving you a solid foundation for a powerful build.

This assembly starts with a 4.250-inch forged 4340 steel crankshaft featuring a center counterweighted design for improved balance and reduced stress. Paired with it are 6.385-inch H-beam connecting rods, known for their strength and reliability under high loads. These rods are secured with 7/16-inch ARP L19 bolts, a popular choice for their exceptional clamping force and durability in high-stress environments. The pistons are forged 2618 aluminum from MAHLE, measuring 4.350 inches with a 43cc dome volume, designed to work with the crank and rods for optimal compression and performance. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your specific build, and King XP series rod and main bearings, which offer robust lubrication and wear resistance for demanding conditions.

This rotating assembly is a comprehensive package for anyone pushing the limits of their Chevy 454. Remember 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 break-in procedures to ensure the longevity and performance of your engine build.
