Overview:

The Eagle Competition Rotating Assembly is a precision-engineered short block kit designed to deliver reliable performance upgrades for a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. This assembly provides enthusiasts and professional builders with a robust foundation for high-performance engine builds, offering enhanced durability and strength over stock components.

Ideal for those seeking to rebuild or upgrade their HEMI engines, this rotating assembly combines forged internals and quality materials to withstand increased power levels and demanding driving conditions. Whether you are building a street performance engine or a track-ready powerplant, this kit offers the core components needed for a dependable and efficient build.

Key Features:

This rotating assembly incorporates several high-quality components and design features that ensure durability and performance:

• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged 4340 steel H-beam connecting rods, 6.125 inches center-to-center, for enhanced rigidity
• Forged aluminum pistons with a dished design and two valve reliefs, optimized for combustion efficiency
• Pistons and rings oversized by 0.010 inches (0.250 mm) for precise bore fitment
• Plasmamoly piston ring facing material for improved wear resistance and sealing
• Floating wrist pins for reduced friction and reliable piston articulation
• Includes piston rings, rod bearings, and main bearings at stock undersize for immediate assembly
• Engine displacement of 6.4L (392 cubic inches) with a bore of 3.927 inches (99.746 mm) and stroke of 4.050 inches
• Designed for use with a 32-tooth reluctor wheel, compatible with factory ignition systems

Construction & Design:

The Eagle Competition Rotating Assembly is built with premium materials and meticulous craftsmanship. The forged 4340 steel crankshaft and connecting rods provide exceptional tensile strength and durability, essential for handling increased horsepower and torque. The H-beam rod design offers an optimal balance of weight and stiffness, reducing flex under high loads.

Forged aluminum pistons feature a dished crown with valve reliefs to maintain proper clearance and combustion chamber volume (+21.20 cc), supporting efficient combustion and preventing detonation. The plasmamoly ring material enhances ring life and sealing capability, contributing to improved compression and oil control.

Installation & Fitment:

This rotating assembly is designed as a direct fit for most Chrysler, Dodge, Jeep, and Ram models equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. Installation requires standard engine assembly procedures and is intended for professional or experienced engine builders. Note that the kit does not include camshaft, lifters, timing components, gaskets, or oil pump, which must be sourced separately.

The assembly is not balanced and does not include a harmonic balancer, flexplate, or flywheel, so these components must be matched and balanced accordingly during build. It is optimized for use with a 32-tooth reluctor wheel for proper ignition timing and sensor compatibility.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Forged aluminum pistons with dished design and valve reliefs
• Piston rings with plasmamoly facing
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This rotating assembly is perfect for automotive enthusiasts, engine builders, and performance shops looking to upgrade or rebuild Chrysler HEMI engines with reliable, high-quality components. It suits applications ranging from street performance to moderate track use, providing a solid foundation for increased power and durability without the need for custom machining or balancing.
