232123927

Overview:

The Eagle Competition Rotating Assembly is engineered to provide a robust and reliable foundation for high-performance Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk variants. Designed for enthusiasts and professional builders seeking durable, precision-crafted components, this rotating assembly delivers the essential internal parts needed to build or upgrade your engine’s bottom end.

Built to exacting standards, this assembly ensures compatibility with engines featuring a 58-tooth reluctor wheel, making it an ideal choice for those aiming to maintain OEM sensor functionality while enhancing engine strength and reliability. Whether you are rebuilding a factory engine or assembling a performance build, this kit offers the core components necessary for a solid foundation.

Key Features:

This rotating assembly combines high-quality materials and precision engineering to meet the demands of performance applications. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged 4340 steel H-beam connecting rods, 6.125 inches center to center
• Forged aluminum pistons with a dished design and two valve reliefs for optimal combustion chamber clearance
• Pistons and rings oversized by 0.010 inches (0.250 mm) for precise bore fitment
• Plasmamoly piston ring facing material for enhanced wear resistance and sealing
• Floating wrist pins for reduced friction and improved piston articulation
• Includes piston rings, rod bearings, and main bearings at stock undersize dimensions for a balanced rebuild
• Rear main seal style: 1-piece for reliable sealing and ease of installation
• Engine displacement: 6.4L / 392 cubic inches, with piston head volume of +6.30cc
• Designed for use with a 58-tooth reluctor wheel to maintain factory ignition timing signals

Construction & Design:

The Eagle Competition Rotating Assembly is crafted with premium materials to withstand the rigors of high-performance and racing environments. The forged 4340 steel crankshaft and connecting rods provide exceptional tensile strength and fatigue resistance, critical for handling increased power and RPM. The H-beam design of the rods offers an optimal balance of stiffness and weight, reducing flex under load.

Forged aluminum pistons are engineered with a dished crown and valve reliefs to optimize combustion efficiency while maintaining adequate clearance for high-lift camshafts. The use of plasmamoly ring material enhances durability and ring seal, contributing to improved compression and reduced blow-by. This assembly is precision machined to tight tolerances, ensuring consistent fitment and performance.

Installation & Fitment:

This rotating assembly is designed as a direct fit for most Chrysler, Dodge, Jeep, and Ram Hemi engines within the 5.7L to 6.4L range, including the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk models. It is intended for engine builders and professional installers familiar with engine assembly procedures. Installation requires standard engine rebuild practices, including proper torque specifications and clearances.

Note that this kit does not include camshaft, lifters, timing components, oil pump, gaskets, or harmonic balancer, so those parts must be sourced separately. The assembly is not balanced, so balancing may be necessary depending on your build requirements.

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
• Piston rings with plasmamoly facing
• Rod bearings (stock undersize)
• Main bearings (stock undersize)
• Floating wrist pins

Ideal For:

This rotating assembly is ideal for performance enthusiasts, engine builders, and racers who require a durable, high-quality bottom end for Chrysler and Dodge Hemi engines. It suits applications ranging from street performance upgrades to track-focused builds where reliability and strength are paramount. Compatible with popular Hemi engine variants, it supports a wide range of power levels and tuning options.

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.
