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 the essential internal components needed for engine rebuilds or upgrades.

Ideal for those aiming to enhance engine strength and longevity under demanding conditions, this kit delivers precision-engineered forged components that stand up to high RPM and increased power outputs. It is perfect for performance builds, street/strip applications, and serious enthusiasts who demand quality and consistency.

Key Features:

This rotating assembly kit combines premium materials and precise manufacturing to ensure optimal engine performance and durability. Key features include:

• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged 4340 steel H-beam connecting rods with a 6.125-inch center-to-center length for enhanced rigidity
• Forged aluminum pistons with dome design and two valve reliefs for improved combustion efficiency
• Plasmamoly piston rings included, sized at 0.010 inch oversize for tight sealing and durability
• Floating wrist pins for reduced friction and reliable piston articulation
• Complete set of rod and main bearings at stock undersize for precise fitment
• Compatible with 58-tooth reluctor wheel setups, ensuring proper engine management system integration
• Balanced internally (excluding external balancing) to maintain smooth engine operation

Construction & Design:

The kit features a forged 4340 steel crankshaft, known for its exceptional toughness and resistance to stress, making it ideal for high-performance and racing applications. The H-beam connecting rods, also forged from 4340 steel, provide a perfect balance of strength and weight, reducing the risk of rod failure under extreme loads.

Forged aluminum pistons with a dome shape and valve reliefs optimize combustion chamber dynamics, improving power delivery and efficiency. The use of plasmamoly piston rings enhances wear resistance and sealing capability, contributing to longer engine life and consistent compression.

Each component is manufactured to tight tolerances to ensure compatibility and reliability when assembled, supporting high RPM operation and increased boost or nitrous applications when combined with appropriate engine modifications.

Installation & Fitment:

This rotating assembly kit is designed as a direct fit for most Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk models. Installation requires professional engine assembly skills and proper machining of the engine block to accommodate the 0.010 inch oversize pistons and rings.

Note that this kit does not include external components such as harmonic balancer, flexplate, flywheel, camshaft, lifters, timing chain, gears, gaskets, or oil pump. These must be sourced separately to complete the engine build. The kit is intended for use with a 58-tooth reluctor wheel for proper engine 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 dome and two valve reliefs
• Plasmamoly piston rings (0.010 inch oversize)
• Floating wrist pins
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This Eagle Competition Rotating Assemblies Kit is ideal for engine builders, performance enthusiasts, and racers who require a robust, high-quality rotating assembly for Chrysler and Dodge Hemi engines. It suits applications ranging from street performance upgrades to serious track and drag racing builds where durability and precision are paramount.

Eagle Specialty Products manufactures high-strength engine components—most notably connecting rods and crankshafts—intended for performance and racing engines. These rotating-assembly upgrades are commonly used in builds that demand higher strength margins for boost, nitrous, sustained RPM, or competition use.
