Overview:

The Eagle Competition Rotating Assembly Kit is engineered for serious enthusiasts and professional builders seeking a reliable, high-quality rotating assembly for Chrysler, Dodge, Jeep, and Ram HEMI engines ranging from 5.7L to 6.4L, including performance variants like the 6.1L SRT8, 6.2L Hellcat, and 6.4L 392. This kit provides the essential forged components needed to build a durable and responsive engine foundation capable of handling increased power and demanding conditions.

Designed specifically for use with a 32-tooth reluctor wheel, this assembly is ideal for those upgrading or rebuilding their HEMI engines with a focus on strength and precision. Whether you are restoring a muscle car, upgrading a truck, or building a high-performance street or track engine, this kit delivers the core rotating parts to support your build.

Key Features:

This rotating assembly kit combines premium materials and precise engineering to ensure durability and performance:

• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged 4340 steel H-beam connecting rods, 6.125 inches center-to-center length
• Forged aluminum pistons with a dished design and two valve reliefs for optimal combustion chamber clearance
• Pistons and rings oversized by 0.010 inches (0.250 mm) for precise bore fitment
• Plasmamoly piston ring facing material for enhanced wear resistance and sealing
• Floating wrist pins for reduced friction and reliable piston articulation
• Includes piston rings, rod bearings, and main bearings at stock undersize dimensions for a complete rotating assembly
• Rear main seal style: 1-piece for reliable sealing and ease of installation
• Designed for engines with a 3.927-inch bore and 4.050-inch stroke, matching a 6.4L/392 displacement

Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with premium forged materials to withstand the rigors of high-performance applications. The crankshaft and connecting rods are crafted from forged 4340 steel, known for its exceptional strength and toughness under extreme loads. The H-beam design of the rods provides an optimal balance of rigidity and weight savings, enhancing engine responsiveness and durability.

The pistons are forged aluminum with a dished crown and two valve reliefs, engineered to maintain proper clearance in high-compression and high-lift camshaft setups. The use of plasmamoly ring material improves ring life and sealing efficiency, which is critical for maintaining compression and reducing blow-by in boosted or naturally aspirated engines.

Installation & Fitment:

This rotating assembly kit is designed to fit a broad range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L HEMI, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat engines, including the Trackhawk. It requires compatibility with a 32-tooth reluctor wheel and is intended for professional engine builders or experienced enthusiasts familiar with engine assembly procedures.

Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so additional parts will be necessary to complete the engine build. Proper machining and balancing are recommended to ensure optimal performance and longevity.

What's Included:

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

Ideal For:

This kit is ideal for engine builders upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram HEMI engines who require a robust rotating assembly capable of handling increased power levels. It suits performance enthusiasts building street, strip, or mild race engines who prioritize strength, reliability, and precision in their rotating components.
