Overview:

The Eagle Competition Rotating Assemblies Kit is engineered for 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 the 6.2L Hellcat & Trackhawk models. This kit provides the essential internal components needed to build or rebuild a robust engine foundation capable of handling increased power and demanding driving conditions.

Designed to fit engines with a 6.5L/396 displacement and a 58-tooth reluctor wheel, this kit offers a balanced combination of forged components and precision machining to ensure durability and performance. It is ideal for those upgrading or restoring their HEMI powerplants with quality parts that meet or exceed OE standards.

Key Features:

This rotating assembly kit combines strength, precision, and compatibility to deliver dependable performance for a variety of 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 for optimized combustion
• Pistons and rings oversized by 0.030 inches (0.760mm) for precise bore fitment
• Plasmamoly piston ring facing material for enhanced wear resistance
• Complete set of piston rings, rod bearings, and main bearings included at stock undersizes
• Floating wrist pins for reduced friction and improved durability
• Rear main seal style: 1-piece for reliable sealing
• Engine stroke of 4.050 inches and bore diameter of 3.947 inches (100.254mm)
• Designed specifically for use with a 58-tooth reluctor wheel

Construction & Design:

The Eagle Competition Rotating Assemblies Kit is built with premium materials and precision engineering to withstand the rigors of high-performance applications. The forged 4340 steel crankshaft and connecting rods provide exceptional tensile strength and fatigue resistance, essential for engines subjected to elevated RPMs and increased cylinder pressures. The H-beam design of the rods enhances rigidity while minimizing weight, contributing to improved engine responsiveness.

Forged aluminum pistons are crafted for durability and thermal efficiency, featuring flat tops with valve reliefs to maintain proper clearance and combustion chamber shape. The use of plasmamoly material on piston rings ensures long-lasting sealing and reduced wear under demanding conditions. Each component is machined to tight tolerances, ensuring optimal fit and function within the engine block.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram HEMI engines with displacements from 5.7L to 6.4L, including performance variants such as the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk. Installation requires standard engine assembly procedures and compatibility with a 58-tooth reluctor wheel setup. Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so those must be sourced separately.

Professional installation is recommended to ensure proper clearances, torque specifications, and balance. This kit is not internally balanced, so external balancing may be necessary depending on the application.

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)
• Floating wrist pins

Ideal For:

This kit is ideal for engine builders, performance enthusiasts, and professional shops looking to assemble or upgrade Chrysler, Dodge, Jeep, or Ram HEMI engines with a durable, high-quality rotating assembly. It suits applications ranging from street performance to moderate racing builds where reliability and strength are paramount. Whether restoring a classic 5.7L HEMI or building a powerful 6.2L Hellcat engine, this kit provides the core components needed for a solid foundation.

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.
