Eagle Chevy 502 4.250in Counterweight Crank 6.385in H-Beam 37cc 4.560in Pistons Rotating Assembly

This is the Eagle Chevy 502 Heavy Duty Rotating Assembly, built for the most demanding competition engines. If you're pushing your big-block Chevy 502 past its limits with exotic fuels, heavy nitrous, or high boost, this assembly is designed to handle the extreme stress.

At its core is a 4.250-inch forged 4340 steel crankshaft, featuring a center counterweighted design to help balance the forces within the engine. Paired with this 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 robust clamping force and durability in high-stress applications. The assembly includes 4.560-inch JE forged pistons, specifically designed with a 37cc dome to achieve a desired compression ratio, and come with plasma-moly file-fit rings for a good seal. For smooth operation and longevity, King XP rod and main bearings are included, offering excellent performance in extreme conditions.

This rotating assembly is a well-built foundation for a serious performance engine build. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
