Overview:

The Eagle Competition Rotating Assembly Kit is engineered for high-performance enthusiasts seeking a reliable and durable upgrade for their Chrysler, Dodge, Jeep, or Ram Hemi engines. Designed to fit a wide range of 5.7L to 6.4L Hemi models—including the 6.1L SRT8, 6.4L 392, and the 6.2L Hellcat and Trackhawk variants—this kit provides a robust foundation for building or rebuilding a powerful engine. It is ideal for those who demand precision, strength, and consistency in their rotating assembly components.

Whether you are preparing for street performance, track use, or serious engine modifications, this kit offers the essential components needed to enhance engine durability and performance potential.

Key Features:

This rotating assembly kit combines quality materials and precise engineering to deliver dependable performance. 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 pistons with a dished design and two valve reliefs, featuring a +12.00cc piston head volume
• Plasmamoly piston rings included, sized at 0.035-inch oversize for improved sealing and wear resistance
• Floating wrist pins for reduced friction and enhanced piston movement
• Stock size rod and main bearings included for precise fitment
• Designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition systems
• Balanced internally (note: this kit is not externally balanced)

Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with premium materials to withstand the rigors of high-performance applications. The crankshaft and connecting rods are forged from 4340 steel, a material known for its exceptional tensile strength and fatigue resistance. This ensures the rotating assembly can handle increased power and RPM without compromising reliability.

The pistons are crafted from forged aluminum, providing a lightweight yet strong component that helps reduce reciprocating mass and improve throttle response. Their dished design with valve reliefs allows for optimal combustion chamber clearance and compatibility with high-compression setups. The plasmamoly piston rings offer enhanced wear resistance and sealing capabilities, contributing to improved engine efficiency and longevity.

Installation & Fitment:

This 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, and 6.2L Hellcat or Trackhawk engines. Installation requires standard engine assembly procedures and should be performed by a professional or experienced engine builder to ensure proper clearances and torque specifications.

Note that the kit does not include harmonic balancer, flexplate, flywheel, camshaft, lifters, timing components, gaskets, oil pump, or assembly lubricant, so these must be sourced separately. It is also designed for use with a 32-tooth reluctor wheel, so verify compatibility with your ignition system before installation.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Forged aluminum pistons with two valve reliefs and +12.00cc volume
• Plasmamoly piston rings (0.035" oversize)
• Floating wrist pins
• Rod bearings (stock size)
• Main bearings (stock size)

Ideal For:

This rotating assembly kit is perfect for engine builders and performance enthusiasts who want to upgrade or rebuild their Hemi engines with high-quality components. It suits those preparing for street performance, drag racing, or track applications where durability and reliability under increased power levels are critical. The kit is also a solid choice for custom engine builds requiring forged internals to handle forced induction or naturally aspirated power upgrades.

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.
