Eagle Chevy 502 4.250in Crank 6.385in H-Beam -20cc 4.500in Pistons Rotating Assembly

If you're building a serious performance engine for your Chevy 502, especially one that will see extreme competition use like heavy nitrous, high boost, or exotic fuels, this Eagle rotating assembly is a solid foundation. It's designed to handle the kind of stress that pushes a standard engine to its limits and beyond.

At the heart of this assembly is a forged 4.250-inch crankshaft made from 4340 steel, known for its strength and durability under high loads. Paired with this are 6.385-inch H-beam connecting rods, which are a popular choice for performance builds due to their robust design. These rods come equipped with 7/16-inch ARP 2000 bolts, a name you can trust for reliable clamping force even under extreme cylinder pressures. The pistons are forged 4.500-inch units from JE, featuring a -20cc inverted dome designed specifically for forced induction applications. They also include plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing in high-stress environments. To top it off, the assembly includes King XP rod and main bearings, which offer improved lubrication and wear resistance for critical rotating components.

This is a heavy-duty assembly built for demanding applications. 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 balancing and assembly procedures to ensure optimal performance and longevity.
