Construction & Design:

This rotating assembly is crafted from high-grade materials chosen for their strength and fatigue resistance. The forged 4340 steel crankshaft provides a solid backbone capable of withstanding high RPMs and increased cylinder pressures. The 6.125" H-beam rods are forged for maximum rigidity and reduced flex under load, while the ARP 8740 bolts ensure the rods remain securely fastened during intense operation.

The pistons are forged from 4032 alloy, known for its excellent thermal conductivity and strength, and feature a 6cc dome to optimize compression ratio and combustion efficiency. Plasma-moly file-fit rings provide superior sealing and wear resistance, contributing to improved oil control and reduced blow-by. King XP bearings are selected for their durability and ability to handle the stresses of racing and forced induction.

Installation & Fitment:

This rotating assembly is designed for the Chrysler 5.7L HEMI engine platform. Professional installation by a qualified machine shop is required, including precision balancing of the assembly before use to ensure optimal engine performance and longevity. Proper balancing minimizes vibrations and stress on engine components, which is critical for high-performance and racing applications.

Installation may require standard engine assembly procedures and checks to ensure compatibility with existing engine components and clearances.
