Eagle Chrysler LM HEMI 4.050in Crank 32 Tth Rlctor 6.125in H-Beam 4.060in Pistons Balanced Assembly

If you're building a high-performance Chrysler LM HEMI engine for serious racing, a balanced rotating assembly is the foundation you need. This assembly from Eagle is designed to handle the stresses of competition, whether you're running nitrous or forced induction. It includes all the critical components that spin together, precisely balanced to ensure smooth operation and longevity under demanding conditions.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.050-inch stroke, providing the displacement increase for more power. It's paired with 6.125-inch H-beam connecting rods, known for their strength and rigidity, which are secured with 7/16-inch ARP 8740 bolts. The pistons are forged 2618 aluminum from Diamond, featuring an inverted dome design with a -26.5cc dish to achieve a specific compression ratio with your cylinder heads, and they come with plasma-moly file-fit rings for improved sealing. King XP rod and main bearings are included, offering robust protection for these high-stress components.

This assembly is balanced as a complete unit, which is crucial for high-RPM operation and reducing vibration. It also features a 32-tooth reluctor wheel, important for engine management systems. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. For a competition engine build, ensuring all components are correctly installed and clearances are checked is vital.
