Overview:

The Eagle Competition Rotating Assembly Kit is engineered for serious enthusiasts and professional builders seeking a reliable, high-quality rotating assembly for Chrysler, Dodge, Jeep, and Ram HEMI engines ranging from 5.7L to 6.4L, including performance variants like the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk models. This kit provides the core rotating components essential for engine rebuilds or performance upgrades, delivering durability and precision for demanding applications.

Designed to handle increased power and stress, this assembly is ideal for those upgrading their engine internals or replacing worn components with forged, race-proven parts. It offers a solid foundation for building a high-performance HEMI engine with confidence.

Key Features:

This rotating assembly kit combines strength, precision, and compatibility to meet the needs of performance builds and engine rebuilds alike. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged 4340 steel H-beam connecting rods with 6.125-inch center-to-center length
• Forged aluminum pistons with a dished design and two valve reliefs, featuring +12.00cc piston head volume
• Pistons and rings oversized by 0.010 inch (0.250 mm) for precision bore fitment
• Plasmamoly piston ring facing material for enhanced wear resistance and sealing
• Floating wrist pins for reliable piston articulation
• Complete set of main and rod bearings at stock undersize for immediate installation
• Balanced internal engine components (excluding external balance) to reduce vibration and improve longevity
• Designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition timing systems

Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with premium materials and precision engineering to withstand the rigors of high-performance and racing environments. The crankshaft and connecting rods are crafted from forged 4340 steel, known for its exceptional tensile strength and fatigue resistance. The H-beam design of the rods provides optimal stiffness and durability under high load conditions.

Forged aluminum pistons are designed with a dished crown and valve reliefs to maintain proper compression ratios and valve clearance, while the plasmamoly ring material enhances ring life and sealing efficiency. The assembly is balanced internally to minimize engine vibrations, contributing to smoother operation and improved component longevity.

Installation & Fitment:

This rotating assembly kit is engineered to fit a wide range of Chrysler, Dodge, Jeep, and Ram engines equipped with 5.7L HEMI, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. It is designed for use with a 32-tooth reluctor wheel and requires no modifications to the engine block bore beyond standard machining for the specified oversize pistons and rings.

Installation should be performed by experienced engine builders or technicians familiar with high-performance HEMI engines to ensure proper clearances, torque specifications, and assembly procedures are followed. Note that this kit does not include camshaft, lifters, timing components, gaskets, or external accessories, which must be sourced separately.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125-inch center-to-center)
• Forged aluminum pistons with two valve reliefs and +12.00cc volume
• Piston rings with plasmamoly facing, oversized by 0.010 inch (0.250 mm)
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is ideal for performance enthusiasts, engine builders, and racers who require a durable and precise rotating assembly for Chrysler and Dodge HEMI engines. It suits applications ranging from street performance upgrades to track and competition builds where reliability and strength are paramount. Whether rebuilding a worn engine or upgrading for increased power, this assembly provides a solid foundation for high-performance engine projects.

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.
