231123937

Overview:

The Eagle Competition Forged Rotating Assembly Kit is engineered for serious enthusiasts and professional builders seeking a robust and reliable rotating assembly for Chrysler, Dodge, Jeep, and Ram Hemi engines. Designed to fit a wide range of 5.7L to 6.4L Hemi models, including high-performance variants like the 6.1L SRT8, 6.2L Hellcat, and 6.4L 392, this kit provides a solid foundation for engine builds that demand durability and strength under high stress.

This kit is ideal for those upgrading or rebuilding their engines with forged components to handle increased power levels, higher RPMs, and extended service life. It offers a comprehensive solution with forged pistons, rods, and crankshaft, ensuring improved reliability and performance potential over stock assemblies.

Key Features:

Built with precision and quality materials, the Eagle Competition Forged Rotating Assembly Kit includes:

• Forged 4340 steel crankshaft for exceptional strength and durability
• Forged 4340 steel H-beam connecting rods with 6.125-inch center-to-center length
• Forged aluminum pistons featuring a dished design with two valve reliefs for optimal combustion chamber clearance
• Piston rings with plasmamoly facing for enhanced wear resistance and sealing
• 0.020-inch (0.510mm) piston and ring oversize for precise bore fitment
• Floating wrist pins for reduced friction and improved piston stability
• Complete set of rod and main bearings at stock undersize dimensions for easy installation
• Designed for use with a 32-tooth reluctor wheel, compatible with factory ignition systems
• Includes all critical rotating assembly components except harmonic balancer, flexplate, flywheel, camshaft, lifters, timing chain/gears, gaskets, oil pump, plastigage, and assembly lubricant

Construction & Design:

The rotating assembly is meticulously crafted using premium forged materials to withstand the rigors of high-performance applications. The crankshaft and connecting rods are forged from 4340 steel, known for its superior tensile strength and fatigue resistance, ensuring longevity even under extreme loads. The pistons are forged aluminum, providing a lightweight yet durable component that helps reduce reciprocating mass and improve throttle response.

The piston design incorporates a dished crown with two valve reliefs to maintain proper clearance and optimize combustion efficiency. The plasmamoly-faced piston rings offer excellent wear characteristics and maintain a tight seal for improved compression and reduced blow-by. This assembly is engineered to fit factory bore sizes with a slight oversize to accommodate standard machining tolerances.

Installation & Fitment:

This rotating assembly kit is designed to fit most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, 6.2L Hellcat, and Trackhawk engines. Installation requires professional engine building experience and proper machining of the engine block to the specified bore size of 3.937 inches (100.000 mm). The kit does not include camshaft, lifters, timing components, or gaskets, so these must be sourced separately to complete the build.

It is important to verify compatibility with your specific engine model and year before purchase. This kit is designed for use with a 32-tooth reluctor wheel and does not include balancing, so additional balancing may be required depending on your build specifications.

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
• Piston rings with plasmamoly facing
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is perfect for engine builders, performance enthusiasts, and racers who require a durable and high-quality rotating assembly for their Chrysler, Dodge, Jeep, or Ram Hemi engines. Whether you are upgrading for increased horsepower, preparing for forced induction, or rebuilding a high-mileage engine, the Eagle Competition Forged Rotating Assembly Kit provides the strength and reliability needed for demanding applications.

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.
