232003927

Overview:

The Eagle Competition Rotating Assembly Kit is engineered for high-performance Chrysler, Dodge, Jeep, and Ram engines equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. Designed to upgrade or rebuild your engine’s rotating components, this kit delivers durable, precision-crafted parts that enhance reliability and power potential. Ideal for enthusiasts and professional builders seeking a robust foundation for performance builds, the kit focuses on quality materials and exacting standards to ensure consistent operation under demanding conditions.

This assembly is tailored for engines with a 6.4L/392 displacement and a 58-tooth reluctor wheel, providing compatibility with a wide range of popular Hemi-based platforms. Whether you are restoring a worn-out engine or building a high-output street or race motor, this kit offers the essential rotating components needed for a solid, dependable build.

Key Features:

Every component in the Eagle Competition Rotating Assembly Kit is selected for strength, precision, and performance. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged aluminum pistons with dome design and two valve reliefs for optimized combustion chamber shape
• H-beam forged 4340 steel connecting rods with a 6.125-inch center-to-center length for enhanced rigidity
• Plasmamoly piston rings included, featuring a 0.010-inch oversize for improved sealing and wear resistance
• Complete set of rod and main bearings at stock size for precise fitment
• Floating wrist pins for reduced friction and reliable piston articulation
• Balanced rotating assembly components (note: assembly is not internally balanced)
• Designed specifically for use with a 58-tooth reluctor wheel to ensure proper engine management system compatibility
• Comprehensive mechanical and electrical failure coverage plan included

Construction & Design:

The kit’s components are crafted from premium materials to withstand the rigors of high-performance applications. The crankshaft and connecting rods utilize forged 4340 steel, a material known for its exceptional tensile strength and fatigue resistance. This ensures the rotating assembly can handle increased power levels and aggressive driving conditions without compromise.

Forged aluminum pistons feature a dome shape with two valve reliefs, optimizing combustion efficiency and clearance for high-lift camshafts. The use of plasmamoly piston rings enhances durability and maintains excellent sealing under elevated temperatures and pressures. Each part is manufactured to tight tolerances, ensuring consistent performance and longevity.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram engines with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk configurations. Installation requires standard engine rebuild procedures and should be performed by a qualified technician to ensure proper clearances and torque specifications. Note that the kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately.

Compatibility with the 58-tooth reluctor wheel is critical for proper engine management system operation. Confirm fitment with your specific vehicle model and year before purchase.

What's Included:

• Forged 4340 steel crankshaft
• Forged aluminum pistons (oversized by 0.010 inch / 0.250 mm)
• Forged 4340 steel H-beam connecting rods (6.125-inch center-to-center length)
• Piston rings with plasmamoly facing
• Rod bearings (stock size)
• Main bearings (stock size)

Ideal For:

This rotating assembly kit is perfect for engine builders, performance enthusiasts, and professional shops aiming to rebuild or upgrade Chrysler, Dodge, Jeep, and Ram Hemi engines. It suits applications ranging from street performance to moderate racing builds where reliability and strength are paramount. The kit provides a solid foundation for increased horsepower and torque while maintaining OEM-style fitment and compatibility.

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.
