Overview:

The Eagle Competition Rotating Assembly is a precision-engineered engine rebuild kit designed for high-performance Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat engines. This assembly is ideal for enthusiasts and professional builders seeking a durable, balanced, and reliable rotating assembly that can withstand the rigors of aggressive driving and racing conditions.

Built to exacting standards, this kit provides a solid foundation for engine rebuilds or upgrades, delivering enhanced strength and longevity. It is engineered to fit most applications using a 32-tooth reluctor wheel, making it a versatile choice for a wide range of performance builds.

Key Features:

This rotating assembly combines high-quality materials and expert craftsmanship to ensure optimal performance and durability. Key features include:

• Engine displacement of 6.9L (421 cubic inches) for increased power potential
• 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 flat-top pistons with two valve reliefs and +4.20cc piston head volume for improved combustion efficiency
• Plasmamoly piston rings included, sized at 0.015-inch oversize for precise sealing and durability
• Balanced rotating assembly for smooth operation and reduced vibration
• Stock size rod and main bearings included for reliable bearing performance
• Floating wrist pins for reduced friction and improved piston articulation
• Designed for use with a 32-tooth reluctor wheel, compatible with most factory and aftermarket ignition systems

Construction & Design:

The Eagle Competition Rotating Assembly is crafted from premium materials to meet the demands of high-performance engines. The crankshaft and connecting rods are forged from 4340 steel, known for its exceptional tensile strength and toughness, ensuring durability under extreme loads. The pistons are made from forged aluminum, offering a lightweight yet strong solution that helps reduce reciprocating mass and improve throttle response.

Each component is precision machined and balanced to exact tolerances, resulting in a smooth-running assembly that minimizes vibration and maximizes engine longevity. The flat-top piston design with valve reliefs optimizes combustion chamber shape for efficient power delivery and clearance.

Installation & Fitment:

This rotating assembly is designed as a direct fit for Chrysler, Dodge, Jeep, and Ram engines with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat displacements. It is compatible with most applications utilizing a 32-tooth reluctor wheel. Installation requires standard engine rebuild procedures and should be performed by a qualified technician to ensure proper clearances and torque specifications.

Note that this kit does not include camshaft, lifters, timing components, gaskets, oil pump, harmonic balancer, flexplate, or flywheel. These items must be sourced separately to complete the engine assembly.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Forged aluminum flat-top pistons with two valve reliefs
• Piston rings (plasmamoly material, 0.015" oversize)
• Rod bearings (stock size)
• Main bearings (stock size)

Ideal For:

This rotating assembly is perfect for performance enthusiasts, engine builders, and racers who demand a robust and balanced foundation for their Chrysler, Dodge, Jeep, or Ram Hemi-based engines. Whether rebuilding a worn engine or upgrading for increased power and durability, this kit offers the quality and reliability needed for street, strip, or track 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.
