232503927

Overview:

The Eagle Competition Rotating Assemblies Kit is engineered for high-performance enthusiasts and professional builders seeking a reliable and robust rotating assembly for Chrysler, Dodge, Jeep, and 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 & Trackhawk, this kit delivers precision and durability for serious engine builds.

This kit provides the essential rotating components needed to upgrade or rebuild your engine’s bottom end, ensuring improved strength and longevity under demanding conditions. Ideal for street performance, racing, or high-output applications, it offers a solid foundation for your engine’s internals.

Key Features:

Built with quality materials and designed to exacting standards, the Eagle Competition Rotating Assemblies Kit includes:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged aluminum flat-top pistons with two valve reliefs and +2.00cc piston head volume for optimized combustion
• H-beam forged 4340 steel connecting rods, 6.125 inches center to center, for enhanced rigidity
• Plasmamoly piston rings included, sized at 0.010 inch oversize for precise sealing
• Complete set of rod and main bearings at stock undersize for proper fitment
• Floating wrist pins for reduced friction and reliable piston articulation
• Designed for use with a 58-tooth reluctor wheel to maintain engine timing accuracy
• Balanced components (note: kit is not internally balanced)
• Compatible with 6.4L/392 engine displacement with a bore of 3.927 inches and stroke of 4.050 inches

Construction & Design:

The rotating assembly is crafted from premium forged materials to withstand high RPMs and extreme loads. The crankshaft and connecting rods are made from forged 4340 steel, known for its exceptional tensile strength and fatigue resistance, ensuring long-lasting performance in demanding environments.

The pistons are forged aluminum with a flat-top design and two valve reliefs, providing optimal clearance and combustion efficiency. The use of plasmamoly piston rings enhances wear resistance and sealing capability, contributing to improved engine compression and reduced blow-by.

Each component is precision machined to tight tolerances, ensuring excellent fitment and smooth operation. The kit is designed for engines requiring a 0.010 inch oversize bore, making it suitable for rebuilds and performance upgrades.

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 performance variants like the 6.1L SRT8 and 6.2L Hellcat & Trackhawk. It requires professional installation and proper engine machining to accommodate the 0.010 inch oversize pistons and rings.

Note that the kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately. It is intended for use with a 58-tooth reluctor wheel and is not internally balanced, so engine balancing considerations should be addressed during assembly.

What's Included:

• Forged 4340 steel crankshaft
• Set of forged aluminum flat-top pistons with valve reliefs
• Forged 4340 steel H-beam connecting rods (6.125" center to center)
• Piston rings (plasmamoly material)
• Rod bearings (stock undersize)
• Main bearings (stock undersize)
• Floating wrist pins

Ideal For:

This kit is perfect for engine builders and performance enthusiasts upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram Hemi engines who require a durable, high-quality rotating assembly. It suits street performance builds, drag racing, road racing, and other high-output applications 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.
