Eagle Chevy 454 1Pc 4.250in Counterwght Crank 6.385in H-Beam 44cc 4.280in Pistons Rotating Assembly

Eagle has a solid reputation for building tough engine components, and this rotating assembly is a prime example of that commitment, especially for serious Chevy 454 builds. If you're pushing the limits with exotic fuels, heavy nitrous use, or high boost applications, this assembly is engineered to handle that kind of stress. It’s designed to be the heart of an engine that needs to perform under the most demanding conditions.

At the core of this assembly is a 4.250-inch forged 4340 steel crankshaft featuring center counterweighting. This design helps to balance the rotating mass more effectively, reducing vibration and stress on your engine's bearings. Paired with this are 6.385-inch H-beam connecting rods, known for their strength and reliability in high-performance applications. These rods come equipped with 7/16-inch ARP L19 bolts, a strong choice for ensuring the rods stay securely fastened under extreme loads. The pistons are forged 2618 JE units, measuring 4.280 inches with a 44cc dome volume, designed to work with the included plasma-moly file-fit rings. To top it off, the assembly includes King XP rod and main bearings, which offer improved performance and durability for high-stress engine builds.

This rotating assembly is a significant upgrade for anyone building a competition-level engine. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and setup to ensure optimal performance and longevity.
