• 7/16" ARP 8740 rod bolts ensuring secure rod retention under high stress
• Forged 4032 Mahle flat-top pistons with a 3.937" bore and -2cc dish for precise compression control
• Plasma-moly file-fit piston rings for excellent sealing and reduced friction
• King XP rod and main bearings engineered for high load capacity and durability

Construction & Design:

The assembly is built using premium forged materials to handle the extreme demands of racing and forced induction. The 4340 forged steel crankshaft offers superior fatigue resistance and strength compared to cast alternatives, making it ideal for high RPM and boost applications. The 6.125" H-beam rods provide a perfect balance of strength and weight, reducing the risk of rod failure under high cylinder pressures.

Mahle’s forged 4032 pistons are known for their excellent thermal conductivity and strength, while the plasma-moly rings ensure a tight seal and reduced wear. The use of King XP bearings further enhances durability, providing reliable performance even under sustained high loads.

Installation & Fitment:

This rotating assembly is designed specifically for the Chrysler 5.7L HEMI engine platform. Professional installation is highly recommended, and the assembly must be balanced by a qualified machine shop prior to use to ensure smooth operation and engine longevity. Proper balancing is critical to prevent vibration and premature wear, especially in high-performance and forced-induction applications.
