231003947

Overview:

The Eagle Competition Rotating Assembly is a high-quality engine build kit designed to upgrade and rebuild most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L to 6.4L Hemi engines, including performance variants like the 6.1L SRT8, 6.4L 392, and the 6.2L Hellcat and Trackhawk models. This assembly is engineered to provide a solid foundation for performance enthusiasts seeking durability and reliability in their engine’s rotating components.

Ideal for engine rebuilds or performance upgrades, this kit offers forged components that enhance strength and longevity under demanding conditions. Whether you’re restoring a classic Hemi or building a high-performance street or track engine, this rotating assembly delivers the precision and quality needed for consistent power delivery and engine balance.

Key Features:

This rotating assembly combines premium materials and precise engineering to ensure optimal performance and durability. Key features include:

• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged 4340 steel H-beam connecting rods with a 6.125-inch center-to-center length for enhanced rigidity
• Forged aluminum dome pistons with a -6.00cc dish volume, designed without valve reliefs for maximum compression
• Plasmamoly piston rings included, sized at 0.030-inch oversize for improved sealing and wear resistance
• Floating wrist pins for reduced friction and reliable piston articulation
• Complete set of rod and main bearings at stock undersize dimensions for a precise fit
• Balanced internal engine components (excluding external balancing) to reduce vibration and improve engine smoothness
• Compatible with a 6.5L/396 engine displacement with a bore of 3.947 inches and stroke of 4.050 inches

Construction & Design:

Every component in this rotating assembly is crafted with performance-grade materials to withstand the rigors of high-output applications. The forged 4340 steel crankshaft and connecting rods offer exceptional tensile strength and durability, essential for handling increased horsepower and torque. The forged aluminum pistons are designed with a dome shape to optimize combustion chamber efficiency and power output.

The piston rings feature plasmamoly facing, a material known for its wear resistance and ability to maintain a tight seal under extreme conditions. The floating wrist pins reduce friction and wear, contributing to the assembly’s overall longevity. Although the assembly is internally balanced, external balancing components such as harmonic balancer, flexplate, flywheel, camshaft, and timing components are not included, allowing customization based on specific build requirements.

Installation & Fitment:

This rotating assembly is engineered to fit a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. Installation requires standard engine rebuild procedures and precise machining to ensure proper clearances and fitment. Because some external components like the harmonic balancer, flexplate, and gaskets are not included, these parts will need to be sourced separately to complete the engine assembly.

Professional installation is recommended to guarantee optimal performance and reliability. This kit is ideal for engine builders and enthusiasts looking to upgrade or rebuild their Hemi engines with high-quality rotating components.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125-inch length)
• Forged aluminum dome pistons (0.030-inch oversize)
• Plasmamoly piston rings
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This rotating assembly is perfect for performance enthusiasts, engine builders, and professional shops aiming to rebuild or upgrade Chrysler, Dodge, Jeep, and Ram Hemi engines. It suits applications ranging from street performance to moderate track use, providing a durable and reliable foundation for increased power and engine longevity.

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.
