Eagle Chevy 400 4.000in Crank 6.000in H-Beam Stroker Rods -5cc 4.165in Pistons Balanced Assembly

If you're building a high-performance Chevy 400 engine for serious racing, a balanced rotating assembly like this one from Eagle is a critical starting point. This assembly includes a forged 4.000-inch crankshaft, 6.000-inch H-beam connecting rods with ARP 2000 bolts, JE forged pistons, file-fit plasma-moly rings, and King XP bearings. Everything is balanced as a complete unit, which is essential for smooth operation and longevity at high RPMs.

The forged 4340 steel crankshaft and H-beam connecting rods are built to handle the stresses of racing, including the demands of nitrous and forced induction. The JE pistons are forged from 2618 aluminum and feature a -5cc flat top design, paired with plasma-moly file-fit rings for a good seal. King XP bearings are included to ensure proper lubrication and reduced friction between the crank and rods, and the main bearings. This assembly is balanced from the factory, saving you a significant step and ensuring the rotating mass is properly weighted for optimal performance and reduced vibration.

This balanced rotating assembly is designed for competition use. Please note that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder to ensure all components meet your specific build requirements and local emissions regulations.
