Eagle Chevy 400 350 Mains 4.000in Crank 6.000in H-Beam Stroker Rod 4.125in Pistons Rotating Assembly

This Eagle Heavy Duty rotating assembly is built for serious performance, starting with a 4.000-inch forged 4340 steel crankshaft. It uses the 350 main journal size, which is a common and well-supported configuration for many Chevy engine builds. This assembly is designed to handle the demands of extreme competition, including exotic fuels, heavy nitrous use, and high boost applications.

The H-beam stroker rods measure 6.000 inches long and come equipped with 7/16-inch ARP 2000 bolts, offering a strong connection between the crank and pistons. Forged 2618 JE pistons with a -10.8cc dome are included, designed for a 4.125-inch bore size. These pistons come with plasma-moly file-fit rings, allowing for precise ring gap adjustment during installation. To complete the package, King XP rod and main bearings are supplied, known for their robust performance in high-stress environments.

This assembly is a solid choice for builders looking to push the limits of their Chevy engine. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
