This Eagle Heavy Duty rotating assembly is built for serious competition engines, whether you're running exotic fuels, heavy nitrous, or high boost. It starts with a forged 4340 steel crankshaft featuring a 3.875-inch stroke, designed to increase displacement and power potential for your Chevy 400 engine.

Complementing the crank are 6.000-inch H-beam connecting rods. These are Eagle's Extreme Stroker rods, known for their strength, and they come equipped with 7/16-inch ARP 2000 bolts, a popular choice for their reliability under high stress. The assembly includes forged 2618 JE pistons with a -10.8cc dome, designed for a 4.125-inch bore. These pistons are paired with plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. For smooth operation and durability, the assembly is fitted with King XP rod and main bearings.

This balanced assembly is a solid foundation for building a high-performance engine. 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.
