Overview:

The Eagle Competition Rotating Assembly Kit is engineered for high-performance enthusiasts seeking a reliable and durable rotating assembly for their Chrysler, Dodge, Jeep, or Ram Hemi engines. Designed to fit a broad range of 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 Hemi models, this kit provides the essential internal components needed to build or upgrade your engine’s bottom end. Whether you are rebuilding for street performance, racing, or heavy-duty applications, this kit delivers quality and precision to ensure consistent power and longevity.

Built with forged components and designed for use with a 32-tooth reluctor wheel, this assembly offers a solid foundation for your engine build, allowing for enhanced durability and performance potential without the need for extensive modifications.

Key Features:

This rotating assembly kit combines premium materials and precise engineering to meet the demands of high-performance Hemi engines. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged 4340 steel H-beam connecting rods with a 6.125-inch center-to-center length
• Forged aluminum flat-top pistons with two valve reliefs and +2.00cc piston head volume
• Pistons and rings oversized by 0.030 inches (0.760 mm) for precision fitment
• Plasmamoly piston ring facing material for enhanced wear resistance
• Floating wrist pins for reduced friction and improved reliability
• Complete set of rod and main bearings included at stock undersize dimensions
• Designed specifically for use with a 32-tooth reluctor wheel to maintain factory ignition timing compatibility

Construction & Design:

The Eagle Competition Rotating Assembly Kit is crafted from high-grade materials to withstand the rigors of performance driving. The crankshaft and connecting rods are forged from 4340 steel, known for its exceptional tensile strength and fatigue resistance, ensuring the assembly can handle increased power and RPM levels. The H-beam design of the connecting rods provides an optimal balance of strength and weight, reducing the risk of rod failure under high stress.

The pistons are forged from lightweight aluminum alloy, featuring a flat-top design with two valve reliefs to optimize combustion chamber clearance and efficiency. The +2.00cc piston volume helps fine-tune compression ratios for performance tuning. Additionally, the plasmamoly ring material enhances durability and sealing, contributing to improved engine longevity and power output.

Installation & Fitment:

This rotating assembly kit is designed as a direct fit for most Chrysler, Dodge, Jeep, and Ram Hemi engines in the 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 displacement range. Installation requires standard engine rebuilding procedures and is intended for use with a 32-tooth reluctor wheel. Note that this kit does not include camshaft, lifters, timing components, or gaskets, so these must be sourced separately.

While the kit is not internally balanced, it is engineered to work with the factory balance setup, making it suitable for rebuilds or performance upgrades without the need for custom balancing. Professional installation is recommended to ensure proper clearances and torque specifications are met.

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 (+2.00cc volume)
• Piston rings with plasmamoly facing, oversized by 0.030 inches
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This rotating assembly kit is ideal for engine builders, performance enthusiasts, and professional shops looking to rebuild or upgrade Chrysler, Dodge, Jeep, or Ram Hemi engines with reliable, high-quality components. It suits applications ranging from street performance to moderate racing builds where durability and precision are critical. The kit’s forged components and compatibility with multiple Hemi variants make it a versatile choice for those aiming to enhance engine strength and longevity.

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.
