Overview:

The Eagle Competition Rotating Assemblies Kit is engineered for high-performance enthusiasts and professional builders seeking a reliable, durable rotating assembly for Chrysler, Dodge, Jeep, and Ram Hemi engines. Designed to fit a broad range of 5.7L to 6.4L Hemi models, including the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk variants, this kit provides a solid foundation for engine builds requiring a 6.5L/394 cubic inch displacement.

Built to exacting standards, this kit offers a comprehensive solution for those upgrading or rebuilding their Hemi engines with forged components that balance strength and performance. It is ideal for applications where durability and precision are paramount, including street performance, mild racing, and custom engine builds.

Key Features:

This rotating assembly kit combines premium materials and precise engineering to deliver dependable performance and longevity. Key features include:

• Forged 4340 steel crankshaft for exceptional strength and fatigue resistance
• Forged aluminum pistons with a dished design and two valve reliefs, optimized for combustion efficiency
• H-beam forged 4340 steel connecting rods, 6.125 inches center to center, for superior rigidity and durability
• Plasmamoly piston rings included, designed to provide excellent sealing and wear resistance
• Precision bore size of 3.937 inches (100.000 mm) with a 0.020 inch (0.510 mm) oversize for custom fitment
• Floating wrist pins for reduced friction and enhanced piston articulation
• Stock size rod and main bearings included for straightforward installation
• Designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition and timing systems

Construction & Design:

The Eagle Competition Rotating Assemblies Kit is crafted using high-grade forged materials to withstand the rigors of high-performance operation. The crankshaft and connecting rods are made from forged 4340 steel, known for its superior tensile strength and toughness, which helps resist bending and twisting forces during high RPM operation.

The pistons are forged from durable aluminum alloy and feature a dished crown with two valve reliefs, allowing for optimal valve clearance and combustion chamber shape. This design supports efficient combustion and helps prevent detonation under boost or high compression conditions. The plasmamoly piston rings provide excellent wear resistance and maintain a tight seal for improved compression and oil control.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including performance variants such as the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk. Installation requires standard engine assembly procedures and is best performed by experienced engine builders or professional shops.

Note that the kit does not include harmonic balancer, flexplate, flywheel, camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately. The assembly is not balanced internally, so external balancing may be necessary depending on your build requirements.

What's Included:

• Forged 4340 steel crankshaft
• Forged aluminum pistons (with +21.20cc piston head volume)
• Forged 4340 steel H-beam connecting rods (6.125" center to center)
• Plasmamoly piston rings (0.020" oversize)
• Rod bearings (stock size)
• Main bearings (stock size)

Ideal For:

This kit is ideal for engine builders and performance enthusiasts upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram Hemi engines who require a robust, forged rotating assembly capable of handling increased power levels. It suits street performance builds, mild to moderate racing applications, and custom engine projects where reliability and strength are critical.
