Overview:

The Eagle Competition Rotating Assembly Kit is engineered for high-performance enthusiasts and professional builders seeking a reliable, durable 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 variants, this kit provides the essential internal components needed for a robust engine build or rebuild.

Ideal for those upgrading or restoring their Hemi engines, this kit delivers precision-crafted components that ensure optimal engine balance and durability under demanding conditions. It is tailored for use with a 32-tooth reluctor wheel, making it compatible with modern ignition systems.

Key Features:

This rotating assembly kit combines quality materials and meticulous engineering to enhance engine reliability and performance. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged aluminum flat-top pistons with two valve reliefs and +4.20cc piston head volume for improved combustion efficiency
• H-beam forged 4340 steel connecting rods with 6.125-inch center-to-center length for enhanced rigidity
• Plasmamoly piston rings included, designed for excellent sealing and wear resistance
• Precision bore size of 4.080 inches (103.632mm) with 0.025-inch (0.640mm) oversize for accurate fitment
• Floating wrist pins for reduced friction and improved piston articulation
• Complete set of rod and main bearings included at stock undersize for immediate installation
• Balanced internal engine components to maintain smooth operation (note: assembly is not externally balanced)
• Designed specifically for 6.9L/423 engine displacement with 4.050-inch stroke

Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with premium 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 high RPM and increased cylinder pressures. The forged aluminum pistons are lightweight yet durable, featuring flat tops with valve reliefs to optimize combustion chamber dynamics and prevent valve-to-piston contact.

Each piston ring is plasma-moly coated, offering superior wear resistance and sealing capabilities to maintain compression and reduce oil consumption. The kit’s components are machined to exacting tolerances, ensuring proper fit and function within the engine block. This attention to detail supports longevity and consistent performance in demanding environments.

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 such as the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk. Installation requires standard engine assembly procedures and is intended for professional or experienced engine builders. Note that the kit does not include camshaft, lifters, timing components, or gaskets, so these must be sourced separately.

The kit is compatible with engines using a 32-tooth reluctor wheel and requires no modifications to the block or external components. Proper balancing and clearances should be verified during assembly to ensure optimal engine operation.

What's Included:

• Forged 4340 steel crankshaft
• Forged aluminum flat-top pistons with valve reliefs
• Forged 4340 steel H-beam connecting rods
• Plasmamoly piston rings
• Rod bearings (stock undersize)
• Main bearings (stock undersize)
• Floating wrist pins

Ideal For:

This kit is perfect for engine builders, performance enthusiasts, and professional shops aiming to build or rebuild high-output Chrysler Hemi engines. Whether upgrading a street machine, preparing a race engine, or restoring a performance vehicle, the Eagle Competition Rotating Assembly Kit provides the core rotating components necessary for a durable and responsive powerplant.

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.
