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 the 6.2L Hellcat and Trackhawk variants, this kit provides the essential internal components needed to build or rebuild a powerful engine with confidence.

Ideal for performance upgrades, engine rebuilds, or custom builds, this kit offers forged components that deliver strength and durability under demanding conditions. It is specifically designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition and timing systems.

Key Features:

This rotating assembly kit combines precision engineering with premium materials to enhance engine reliability and performance. Key features include:

• Forged 4340 steel crankshaft for exceptional strength and fatigue resistance
• Forged aluminum pistons with a dished design and two valve reliefs for optimal combustion chamber clearance
• H-beam forged 4340 steel connecting rods, 6.125 inches center to center, for superior rod stability and durability
• Plasmamoly piston rings included, sized at 0.030 inch oversize for improved sealing and wear resistance
• Complete set of rod and main bearings at stock undersize for precise fitment
• Floating wrist pins for reduced friction and enhanced piston articulation
• Balanced internal engine components (excluding external balancing) to maintain smooth operation
• Designed for 6.5L/396 engine displacement with a bore of 3.947 inches (100.254 mm) and a stroke of 4.050 inches
• Compatible with factory rear main seal style (1-piece)

Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with high-quality forged materials to withstand the rigors of high-performance and racing applications. The crankshaft and connecting rods are crafted from forged 4340 steel, known for its superior tensile strength and toughness, ensuring long-lasting durability under extreme loads.

Forged aluminum pistons provide a lightweight yet robust solution, reducing reciprocating mass and improving throttle response. The pistons feature a dished crown with two valve reliefs, optimizing combustion chamber volume and valve clearance. Plasmamoly piston rings enhance sealing efficiency and wear resistance, contributing to improved engine longevity.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. It requires a 32-tooth reluctor wheel for proper ignition timing and sensor compatibility. Installation should be performed by experienced engine builders or professionals familiar with high-performance engine assembly to ensure proper clearances and torque specifications are met.

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