Overview:

The Eagle Competition Rotating Assembly Kit is engineered for high-performance enthusiasts and professional builders seeking a durable and reliable rotating assembly for Chrysler, Dodge, Jeep, and Ram Hemi engines. Designed to fit a broad range of 5.7L to 6.4L Hemi models, including the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk, this kit provides a solid foundation for engine builds requiring forged components and precision craftsmanship.

This kit is ideal for those upgrading or rebuilding their engines with a focus on strength and longevity under demanding conditions. It offers a comprehensive solution with forged pistons, crankshaft, and connecting rods, ensuring enhanced durability and performance potential.

Key Features:

Built to meet the rigorous demands of performance applications, the Eagle Competition Rotating Assembly Kit includes:

• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged aluminum pistons with a dished design and two valve reliefs for optimized combustion chamber clearance
• H-beam forged 4340 steel connecting rods with a 6.125-inch center-to-center length for enhanced rigidity
• Plasmamoly piston rings providing excellent wear resistance and sealing capabilities
• Piston and ring oversize of 0.020 inches (0.510 mm) for precise bore fitment
• Floating wrist pins for reduced friction and improved piston articulation
• Complete set of rod and main bearings at stock undersize for reliable bearing performance
• Designed for use with a 58-tooth reluctor wheel, ensuring compatibility with factory ignition and timing systems

Construction & Design:

The rotating assembly is meticulously crafted using premium materials to withstand the stresses of high-performance and racing environments. The forged 4340 steel crankshaft and connecting rods provide exceptional tensile strength and durability, reducing the risk of failure under high RPM and load conditions. The forged aluminum pistons are lightweight yet robust, featuring a dished crown with valve reliefs to maintain proper clearance and optimize combustion efficiency.

Each piston ring is plasma-moly coated to enhance wear resistance and maintain a tight seal, contributing to improved compression and reduced oil consumption. The assembly is balanced internally to ensure smooth operation, although it is not externally balanced, making it compatible with stock balance configurations.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including popular performance variants such as the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk models. Installation requires standard engine rebuilding procedures and should be performed by experienced technicians to ensure proper clearances and torque specifications.

Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately. It is also designed for use with a 58-tooth reluctor wheel, so verify compatibility with your vehicle’s ignition system before installation.

What's Included:

• Forged 4340 steel crankshaft
• Set of forged aluminum pistons (dish style with valve reliefs)
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Plasmamoly piston rings (oversized 0.020 in.)
• Rod and main bearings (stock undersize)

Ideal For:

This kit is perfect for engine builders and performance enthusiasts who require a robust rotating assembly for street, strip, or mild race applications. It suits those upgrading their Hemi engines for increased durability and reliability without extensive modifications. Whether rebuilding a 5.7L Hemi or upgrading a 6.4L 392 or Hellcat engine, this kit provides a strong foundation for enhanced engine performance and longevity.
