Eagle Chevy 400 4.000in Crank 6.000in H-Beam Stroker Rods -20cc 4.155in Pistons Balanced Assembly

This balanced rotating assembly from Eagle includes a forged 4.000-inch crankshaft, 6.000-inch H-beam connecting rods with 7/16-inch ARP 2000 bolts, forged 4032 Mahle pistons with an inverted dome design for -20cc volume and a 4.155-inch bore, plasma-moly file-fit piston rings, and King XP rod and main bearings. This complete package is designed to handle the demands of racing applications, including those using nitrous oxide or forced induction systems.

The forged 4340 steel crankshaft offers a strong foundation for high-performance builds, while the H-beam connecting rods are built for extreme duty and have extra clearance for stroker applications. The Mahle pistons are forged from 4032 aluminum, known for its strength and durability under high temperatures and pressures, and feature an inverted dome to achieve a -20cc volume, which helps manage compression ratios. The included plasma-moly file-fit rings allow for precise gap setting to match your specific engine build and ensure optimal sealing. King XP bearings are specified for their robust performance in demanding conditions.

This assembly is balanced from the factory, saving you a significant step in the engine building process. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity and performance of your engine.
