Eagle Chevy 502 4.250in Counterweight Crank 6.535in H-Beam 46cc 4.600in Pistons Rotating Assembly

If you're building a serious Chevy 502 big block for extreme duty, this Eagle rotating assembly is a solid foundation. It's designed to handle the intense demands of exotic fuels, heavy nitrous use, or high boost applications, giving you the confidence to push your engine hard. This is a well-built package that brings together critical components for a high-performance build.

At the heart 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 stress on the main bearings and improving overall engine smoothness under load. Paired with the crank are 6.535-inch H-beam connecting rods, known for their strength and reliability in high-stress environments. These rods are secured with 7/16-inch ARP L19 bolts, a popular choice for their exceptional clamping force and durability under extreme conditions. The pistons are forged 2618 aluminum from JE, featuring a 46cc dome volume and a 4.600-inch bore size, designed with gas ports to help with ring seal. This assembly also includes plasma-moly file-fit piston rings, which offer good sealing and wear characteristics, and King XP series rod and main bearings, selected for their robust performance in demanding applications.

This rotating assembly is a significant step up for anyone looking to build a competition-level engine. Keep in mind 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 balancing procedures to ensure optimal performance and longevity.
