Eagle Chevy 400 4.000in Crank 6.000in H-Beam Stroker Rods -5cc 4.125in Pistons Rotating Assembly

This is the Eagle Chevy 400 Competition Rotating Assembly, part number 12056000. It's built for serious performance applications, including racing with nitrous or forced induction. This assembly includes a 4.000-inch forged 4340 crankshaft, which is the foundation for increasing displacement and torque. The H-beam stroker rods are 6.000 inches long and feature extreme clearance for high-performance builds, secured with 7/16-inch ARP 2000 bolts.

The pistons are forged 4032 aluminum from MAHLE, designed as flat-top with a -5cc volume to achieve a specific compression ratio with your cylinder heads. They come with plasma-moly file-fit rings, giving you the flexibility to set proper tension for your engine's needs. To complete the rotating assembly, King XP rod and main bearings are included, known for their durability and performance under load. This is a well-built package designed to handle the stresses of competition.

When installing this assembly, remember that the pistons come with file-fit rings, meaning you'll need to gap them to your specific application. This allows for precise control over ring seal and blow-by. Please 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.
