• Forged 4032 Mahle pistons with 6cc dome design and 3.927" compression height for optimized combustion
• Plasma-moly file-fit piston rings ensuring excellent sealing and reduced friction
• King XP rod and main bearings engineered for high load capacity and durability
• 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 withstand the stresses of high-performance and racing applications. The 4340 forged steel crankshaft offers exceptional fatigue resistance and strength, critical for engines running forced induction or nitrous oxide. The 6.125" H-beam rods are forged for maximum rigidity and durability, while the 7/16" ARP 8740 bolts ensure secure rod-to-crank connections under extreme loads.

Mahle forged pistons made from 4032 alloy provide excellent thermal stability and strength, with a 6cc dome design to optimize compression ratios for performance tuning. The plasma-moly rings are file-fit for precise sealing and reduced wear, contributing to improved engine efficiency and longevity. King XP bearings are selected for their ability to handle high RPM and load conditions common in racing engines.

Installation & Fitment:

This rotating assembly is designed specifically for the Chrysler 5.7L HEMI engine platform. Installation should be performed by a professional engine builder or machinist, as the assembly requires balancing before use to ensure smooth operation and longevity. Proper balancing is critical to prevent vibrations and premature wear, especially in high-performance or forced-induction applications.

While the assembly fits the 5.7L HEMI, additional engine components and tuning may be necessary to fully optimize performance depending on your build goals.
