Eagle Chevy 400 4.000in Crank 6.000in H-Beam Stroker Rods 4cc Dome 4.155in Pistons Balanced Assembly

Starting with a forged 4340 steel crankshaft featuring a 4.000-inch stroke, this balanced rotating assembly from Eagle is built for serious performance, especially in racing applications that might use nitrous or forced induction. The 6.000-inch H-beam connecting rods are designed with extreme stroker clearances, ensuring they can handle the demands of high-RPM operation. These rods are secured with 7/16-inch ARP 2000 bolts, a well-known choice for their strength and reliability under stress.

The assembly includes forged 4032 aluminum pistons from Mahle, each with a 4cc dome and a 4.155-inch bore size. These pistons come with plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering solid lubrication and wear protection for the critical rotating components. This entire assembly is balanced from the factory, saving you a significant step in the engine building process and ensuring smooth operation.

This balanced rotating assembly is a robust foundation for a high-performance Chevy 400 engine build. Please note that this assembly is not CARB approved and cannot be shipped to California. It is also subject to California's Prop 65 warning.
