Eagle Chevy 400 4.000in Crank 6.000in I-Beam Rods 6.2cc Dome 4.165in Pistons Rotating Assembly

Built around a 4.000-inch forged 4340 steel crankshaft, this Eagle Pro Street rotating assembly is a solid foundation for a naturally-aspirated racing engine. The 4340 forged steel construction means it can handle the stresses of high-RPM operation without flexing. This assembly is designed for performance builds where reliability under demanding conditions is key.

Complementing the crankshaft are 6.000-inch I-beam connecting rods, also forged from 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and ability to maintain clamping force under extreme loads. The pistons are forged 2618 aluminum from JE, featuring a 6.2cc dome and a 4.165-inch bore size, which are crucial for achieving specific compression ratios. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. King XP rod and main bearings are included, offering robust protection for the rotating assembly's critical surfaces.

This assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. Please consult your engine builder or refer to manufacturer specifications for complete installation details and compatibility with your specific engine block and cylinder heads.
