Eagle Chevy 400 350 Mains 4.000in Crank 6.000in H-Beam Stroker Rod 4.165in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance, especially in racing applications that might use nitrous or forced induction. The 4340 forged steel is a strong material choice, offering excellent durability and resistance to the stresses of high-RPM operation and significant power adders.

Paired with this crank are 6.000-inch H-beam stroker clearanced rods, which are also forged from 4340 steel. These rods feature 7/16-inch ARP 2000 bolts, known for their strength and reliability under extreme loads. The pistons are forged 2618 aluminum with a -5cc flat top design, ready for a 4.165-inch bore. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs and boost levels. King XP rod and main bearings are included, providing robust lubrication and wear protection for the critical rotating components.

This assembly is designed for Chevy 400 blocks using 350 mains, making it a comprehensive package for a performance engine build.
