Key Features:

This rotating assembly kit combines premium materials and precision engineering to ensure optimal performance and longevity. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged 4340 steel H-beam connecting rods with 6.125-inch center-to-center length
• Forged aluminum pistons with dome design and two valve reliefs for enhanced combustion efficiency
• Pistons and rings oversized by 0.020 inches (0.510 mm) for precise fitment
• Plasmamoly-faced piston rings for improved wear resistance and sealing
• Floating wrist pins for reduced friction and reliable operation
• Includes rod and main bearings at stock undersize for immediate installation
• Engine displacement of 6.5L (394 cubic inches) with a bore of 3.937 inches (100 mm) and stroke of 4.050 inches
• Designed for use with a 1-piece rear main seal style

Construction & Design:

The Eagle Competition Rotating Assemblies Kit is meticulously crafted using high-grade materials 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 increased horsepower and torque.

Forged aluminum pistons feature a dome shape with valve reliefs, optimizing combustion chamber dynamics and allowing for higher compression ratios. The plasmamoly piston ring facing enhances durability and maintains a tight seal under extreme conditions. Each component is machined to exact tolerances to ensure balanced operation and longevity, although this particular kit is not internally balanced.

Installation & Fitment:

This rotating assembly kit is designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines, including 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 models. It requires compatibility with a 32-tooth reluctor wheel and a 1-piece rear main seal style. Installation should be performed by experienced engine builders or professionals to ensure proper assembly and clearances.

Note that this kit does not include components such as the harmonic balancer, flexplate, flywheel, camshaft, lifters, timing chain and gears, oil pump, gaskets, or assembly lubricant. These parts must be sourced separately to complete the engine build.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125-inch center-to-center)
• Forged aluminum dome pistons with two valve reliefs (oversized by 0.020 inches)
• Piston rings with plasmamoly facing
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is perfect for performance enthusiasts, engine builders, and professional shops looking to upgrade or rebuild Chrysler, Dodge, Jeep, and Ram Hemi engines with durable, forged 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.
