Eagle Chrysler LM HEMI 4.050in Crank 32 Tth Reluctor 6.125in H-Beam 4.090in Pistons Bal Assembly

If you're building a serious performance Chrysler LM HEMI engine, especially one intended for racing, nitrous, or forced induction, a balanced rotating assembly like this one from Eagle is a critical starting point. This assembly bundles together the core components that spin inside your engine's crankcase, ensuring they work together harmoniously for maximum power and durability under demanding conditions.

Eagle starts with a forged 4340 steel crankshaft, measuring 4.050 inches, which is known for its strength and ability to handle high stress. It's paired with 6.125-inch H-beam connecting rods, a popular choice for their robust design, which come with 7/16-inch ARP 8740 bolts for secure fastening. The pistons are forged from 2618 aluminum by Diamond, featuring a -4.2cc flat top design and a 4.090-inch bore size, complete with plasma-moly file-fit rings for improved sealing. To ensure everything spins smoothly and with minimal friction, King XP rod and main bearings are included. This entire assembly is balanced at the factory, saving you a significant step and ensuring proper operation right out of the box.

This balanced rotating assembly is designed for high-output applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder or refer to Eagle's specific installation guidelines to ensure proper fitment and assembly into your LM HEMI block.
