• 7/16" ARP 8740 rod bolts for superior clamping force and reliability
• Forged 4032 Mahle pistons with -12cc inverted dome design and 4.080" bore size
• Plasma-moly file-fit piston rings for enhanced sealing and reduced friction
• King XP rod and main bearings engineered for high-performance applications
• Assembly requires professional balancing by a qualified machine shop prior to installation

Construction & Design:

The Eagle rotating assembly is meticulously crafted using premium forged materials to ensure maximum strength and durability under extreme conditions. The 4340 forged steel crankshaft offers excellent resistance to twisting and fatigue, critical for high-RPM and forced induction engines. The 6.125" H-beam rods provide a robust connection between the crank and pistons, engineered to handle elevated cylinder pressures.

Mahle forged pistons made from 4032 alloy feature an inverted dome design with a -12cc volume to optimize compression ratios and combustion efficiency. Plasma-moly file-fit rings enhance ring seal and reduce wear, contributing to improved oil control and power output. The use of ARP 8740 rod bolts ensures secure fastening under high stress, while King XP bearings provide reliable support for rotating components.

Installation & Fitment:

This rotating assembly is specifically designed for the Chrysler 6.1L HEMI engine platform. Professional installation is highly recommended, including precise balancing of the assembly by a qualified machine shop before use to ensure smooth operation and longevity. Proper installation will maximize the performance and durability benefits of this high-quality rotating assembly.
