About this part

Product Details

Starting with a forged 4340 steel crankshaft featuring a 3.875-inch stroke and 350 main journal size, this Eagle rotating assembly is built for serious power. It's designed to handle the demands of extreme competition engines, whether you're running exotic fuels, heavy nitrous, or high boost applications. The crankshaft is paired with 6.000-inch H-beam stroker rods, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP 2000 bolts, a popular choice for their robust clamping force and durability.

The assembly includes forged 2618 aluminum pistons from JE, featuring a -10.8cc dome and a 4.185-inch bore size. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs and ensure optimal sealing. To complete the package, King XP rod and main bearings are included. These bearings offer excellent load-carrying capacity and wear resistance, crucial for maintaining oil pressure and protecting the crankshaft and rod journals under extreme conditions. This comprehensive rotating assembly is a solid foundation for building a high-performance Chevy engine.
