Starting with a forged 4340 steel crankshaft featuring a 3.875-inch stroke and 350 main journal size, this balanced rotating assembly from Eagle is built for serious performance. It’s designed to handle the demands of extreme competition engines, whether you're running exotic fuels, heavy nitrous applications, or high boost levels. The robust construction means it’s ready for whatever you throw at it.

Complementing the strong crank are 6.000-inch H-beam stroker rods. These aren't your average rods; they're built for extreme duty and come equipped with 7/16-inch ARP 2000 bolts, known for their strength and reliability under high stress. The assembly also includes forged 2618 JE pistons with a -5.6cc dome, designed for a 4.165-inch bore. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific build. For smooth operation and durability, King XP rod and main bearings are included, providing solid support for the rotating assembly.

This assembly is balanced from the factory, saving you a significant step in the engine building process. It's important to note that this assembly is not CARB approved and cannot be shipped to California.
