232503937

Overview:

The Eagle Competition Rotating Assemblies Kit is engineered for serious 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, 6.2L Hellcat, and 6.4L 392. This kit provides the essential forged components needed to build or rebuild a robust 6.5L/394 cubic inch displacement engine, delivering durability and strength for high-performance applications.

Designed to meet the demands of both street and track use, this kit offers a solid foundation for engine builds requiring a 58-tooth reluctor wheel setup. It is ideal for those upgrading or replacing their rotating assemblies with premium forged internals that ensure long-lasting performance under increased power and stress.

Key Features:

This rotating assembly kit combines precision engineering with quality materials to enhance engine reliability and performance. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged aluminum pistons with flat tops and two valve reliefs for optimal combustion
• H-beam forged 4340 steel connecting rods, 6.125 inches center to center
• Plasmamoly piston rings included, sized at 0.020 inch oversize for precise fitment
• Complete set of rod and main bearings at stock undersize for ease of installation
• Floating wrist pins for reduced friction and enhanced piston stability
• Balanced internal engine components (excluding external balancing)
• Designed specifically for use with a 58-tooth reluctor wheel
• Includes pistons, rings, crankshaft, connecting rods, rod bearings, and main bearings

Construction & Design:

The kit features a forged 4340 steel crankshaft known for its exceptional toughness and resistance to fatigue, making it suitable for high-RPM and high-stress environments. The connecting rods are also crafted from forged 4340 steel with an H-beam design, providing an excellent strength-to-weight ratio and rigidity to withstand aggressive driving and racing conditions.

Forged aluminum pistons are precision-machined with flat tops and two valve reliefs to optimize combustion chamber efficiency and prevent valve-to-piston contact. The use of plasmamoly piston rings enhances wear resistance and sealing capabilities, contributing to improved engine longevity and performance.

Installation & Fitment:

This rotating assembly kit is designed as a direct fit for 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 assembly practices, including proper torque specifications and clearances. Note that this kit does not include camshaft, lifters, timing components, gaskets, oil pump, harmonic balancer, flexplate, or flywheel, which must be sourced separately.

It is recommended to verify compatibility with your specific vehicle and engine configuration before purchase. The kit is intended for use with a 58-tooth reluctor wheel and is not balanced externally, so additional balancing may be necessary depending on your build.

What's Included:

• Forged 4340 steel crankshaft
• Forged aluminum pistons (flat top with valve reliefs)
• Forged 4340 steel H-beam connecting rods (6.125" center to center)
• Piston rings (plasmamoly, 0.020 inch oversize)
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is perfect for engine builders, performance enthusiasts, and professional shops looking to assemble or upgrade Chrysler-based HEMI engines with durable, high-quality rotating components. It suits applications ranging from street performance to moderate racing builds where reliability and strength are paramount.

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.
