Eagle Chevy 400 350 Mains 4.000in Crank 6.000in H-Beam Stroker Rod 4.155in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance. The 4340 steel is a strong choice for crankshafts, offering good durability and resistance to fatigue, especially under high stress. This assembly is designed for Chevy 400 and 350 main applications, meaning it's intended to fit engines configured with those main bearing sizes.

Complementing the crankshaft are 6.000-inch H-beam connecting rods. These rods are forged from 4340 steel as well and feature a stroker clearance design, which is important for accommodating the longer stroke of the crankshaft without interference. They come equipped with 7/16-inch ARP 2000 bolts, known for their strength and reliability in high-performance engine builds. The pistons are forged 4032 aluminum with an inverted dome design, featuring a -20cc dish to help achieve a desired compression ratio. They include plasma-moly file-fit piston rings, which allow for precise gap setting to match your specific engine build. The assembly also comes with King XP rod and main bearings, offering solid lubrication and wear protection.

This rotating assembly is a well-built package for racing applications, including those using nitrous oxide or forced induction. It's important to 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 to ensure optimal performance and longevity.
