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 to build or rebuild a powerful engine foundation. It is ideal for those upgrading or restoring their HEMI engines with forged, race-ready parts that deliver strength and precision.

Built to exacting standards, this kit offers a balanced rotating assembly (internally balanced) with forged components that enhance durability and performance under demanding conditions. Whether you are assembling a street performance engine or a race-ready powerplant, this kit provides the core components necessary for a robust build.

Key Features:

This rotating assembly kit combines high-quality materials and precision engineering to ensure optimal engine performance and longevity. Key features include:

• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged aluminum pistons with a dished design and two valve reliefs for improved combustion efficiency
• H-beam forged 4340 steel connecting rods, 6.125 inches center-to-center length, for enhanced durability
• Pistons and rings oversized by 0.010 inches (0.250mm) for precise bore fitment
• Plasmamoly piston ring facing material for excellent wear resistance and sealing
• Floating wrist pins for reduced friction and reliable piston articulation
• Includes rod and main bearings at stock undersize for direct replacement
• Designed for use with a 58-tooth reluctor wheel, compatible with factory ignition systems
• Complete rotating assembly kit sold as a package for convenience and compatibility

Construction & Design:

The Eagle Competition Rotating Assemblies Kit is crafted with premium materials selected for strength and reliability. The forged 4340 steel crankshaft and connecting rods provide exceptional toughness to withstand high RPM and increased cylinder pressures. Forged aluminum pistons are engineered with a dished crown and valve reliefs to optimize combustion chamber volume and prevent valve-to-piston contact.

Each piston ring set features plasmamoly facing, ensuring a durable seal against cylinder walls while minimizing wear. The floating wrist pins reduce friction and allow smooth piston movement. The entire assembly is internally balanced, ensuring smooth engine operation and reducing vibration for improved longevity.

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. It is compatible with engines utilizing a 58-tooth reluctor wheel.

Installation requires standard engine assembly procedures and precision machining to ensure proper clearances and fitment. Note that this kit does not include camshaft, lifters, oil pump, gaskets, or other ancillary components, so those must be sourced separately. Professional installation is recommended to achieve optimal engine performance and reliability.

What's Included:

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

Ideal For:

This kit is perfect for engine builders, performance enthusiasts, and racers who require a durable, high-quality rotating assembly for Chrysler and Dodge HEMI engines. It suits applications ranging from street performance upgrades to serious track and competition builds. If you are rebuilding or upgrading a 5.7L to 6.4L HEMI engine and need a reliable foundation with forged internals, this Eagle Competition kit offers a comprehensive solution.

Eagle Specialty Products manufactures high-strength engine components—most notably connecting rods and crankshafts—intended for performance and racing engines.
