• Forged 4340 steel crankshaft for superior strength and fatigue resistance
• Forged 4340 steel H-beam connecting rods with a 6.125-inch center-to-center length
• Forged aluminum pistons with dome design and two valve reliefs for improved combustion efficiency
• Plasmamoly piston rings with 0.010-inch oversize for enhanced sealing and wear resistance
• Stock size rod and main bearings included for precise fitment
• Floating wrist pins for reliable piston articulation
• Compatible with 32-tooth reluctor wheel setups
• Balanced internally (note: this kit is not externally balanced)
• Engine displacement: 6.4L / 392 cubic inches with a 3.927-inch bore and 4.050-inch stroke

Construction & Design:

The Eagle Competition kit is built with high-quality 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 toughness and resistance to stress and fatigue. The pistons are forged aluminum, providing a lightweight yet durable solution that helps reduce reciprocating mass and improve throttle response.

The piston design features a dome shape with two valve reliefs, optimizing combustion chamber volume and clearance for high compression ratios. The plasmamoly piston rings offer excellent wear resistance and sealing capabilities, contributing to improved engine efficiency and longevity. This kit is engineered to maintain factory bearing sizes, ensuring compatibility with existing engine components and simplifying installation.

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 or Trackhawk engines. Installation requires standard engine rebuild procedures and is best performed by experienced technicians or engine builders. The kit is intended for use with a 32-tooth reluctor wheel and does not include camshaft, lifters, timing components, or gaskets, which must be sourced separately.

Note that the harmonic balancer, flexplate, and flywheel are not included, so these components should be reused or replaced as needed during assembly. Proper balancing and clearances should be verified during installation to ensure optimal engine performance and reliability.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Forged aluminum pistons with dome design and valve reliefs
• Plasmamoly piston rings (0.010" oversize)
• Rod bearings (stock size)
• Main bearings (stock size)

Ideal For:

This kit is ideal for performance enthusiasts, engine builders, and professional shops looking to upgrade or rebuild Chrysler, Dodge, Jeep, or Ram Hemi engines with durable, high-quality rotating components. It suits applications ranging from street performance builds to moderate racing setups 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.
