Key Features:

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

• Forged 4340 steel crankshaft for superior strength and durability
• 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
• Piston rings made from plasmamoly material for enhanced wear resistance
• Piston and ring oversize of 0.025 inches (0.640 mm) for precise bore fitment
• Includes rod and main bearings at stock undersize dimensions for a perfect fit
• Designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition systems
• Balanced internally (note: this kit is not externally balanced)
• Rear main seal style: 1-piece for reliable sealing

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 tensile strength and fatigue resistance. The pistons are forged aluminum, offering a lightweight yet durable solution that helps reduce reciprocating mass and improve throttle response.

The pistons feature a dished design with two valve reliefs, allowing for increased compression ratio flexibility and safe valve clearance. The plasmamoly piston rings provide excellent sealing and wear resistance, contributing to long engine life and consistent performance. This kit is engineered to fit a 6.9L/423 cubic inch displacement with a bore of 4.080 inches (103.632 mm) and a stroke of 4.050 inches, matching the specifications of many popular HEMI builds.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most 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 assembly procedures and should be performed by a professional or experienced engine builder to ensure proper clearances and torque specifications.

Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so those items must be sourced separately. It is intended for use with a 32-tooth reluctor wheel and does not include harmonic balancer, flexplate, or flywheel.

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 (plasmamoly material, 0.025" oversize)
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is perfect for engine builders and performance enthusiasts looking to upgrade or rebuild their HEMI engines with high-quality forged components. It suits applications ranging from street performance to moderate racing builds where durability and reliability are paramount. The Eagle Competition Rotating Assembly Kit provides a strong foundation for increased power output and engine longevity in Chrysler, Dodge, Jeep, and Ram HEMI-powered vehicles.

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.
