235143927

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. This comprehensive kit provides the essential rotating components needed to build or upgrade your engine’s bottom end with precision and durability. Designed for enthusiasts and professional builders seeking reliable strength and consistent performance, it offers a solid foundation for increased power and engine longevity.

Whether you are rebuilding a factory engine or assembling a custom performance build, this kit delivers high-quality forged components that meet demanding standards. It is ideal for those who want to maintain OEM fitment while upgrading internal parts for enhanced durability and reliability under high-stress conditions.

Key Features:

This rotating assembly kit combines premium materials and precise engineering to ensure optimal performance and compatibility with your Hemi engine. Key features include:

• Forged 4340 steel crankshaft for superior strength and durability
• Forged aluminum pistons with a dished design and two valve reliefs for improved combustion efficiency
• H-beam forged 4340 steel connecting rods with a 6.125-inch center-to-center length for enhanced rigidity
• Plasmamoly piston rings included, sized at 0.010-inch oversize for tight sealing and wear resistance
• Complete set of rod and main bearings at stock undersize dimensions for precise fitment
• Floating wrist pins for reduced friction and improved piston articulation
• Designed for use with a 58-tooth reluctor wheel, ensuring compatibility with factory ignition timing systems
• Balanced components (excluding external balancing) to maintain engine smoothness and reduce vibration

Construction & Design:

The kit’s components are crafted from premium forged materials to withstand the rigors of high-performance applications. The crankshaft is made from forged 4340 steel, known for its exceptional toughness and fatigue resistance, making it ideal for engines subjected to increased power and RPM. The pistons are forged aluminum with a dished crown and valve reliefs, optimizing combustion chamber volume and clearance for aggressive cam profiles.

Connecting rods utilize an H-beam design forged from 4340 steel, providing a perfect balance of strength and weight savings. The piston rings feature plasmamoly facing, which enhances wear resistance and sealing under high cylinder pressures. This attention to material quality and design ensures the assembly can handle demanding street or track conditions.

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. It requires professional installation and proper machining of the engine block to accommodate the 0.010-inch oversize pistons. The kit does not include external components such as harmonic balancer, flexplate, flywheel, camshaft, or oil pump, so these must be sourced separately.

Careful attention to torque specifications, bearing clearances, and balancing procedures is essential to ensure optimal engine performance and longevity. This kit is intended for use with a 58-tooth reluctor wheel and is compatible with factory ignition and timing systems.

What's Included:

• Forged 4340 steel crankshaft
• Set of forged aluminum pistons (dished with two valve reliefs)
• Forged 4340 steel H-beam connecting rods (6.125-inch center-to-center)
• Piston rings with plasmamoly facing, 0.010-inch oversize
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is perfect for engine builders, performance enthusiasts, and professional shops looking to upgrade or rebuild Chrysler, Dodge, Jeep, and Ram Hemi engines with reliable, high-strength rotating components. It suits applications ranging from street performance to moderate track use where durability and OEM compatibility are priorities. The Eagle Competition Rotating Assembly Kit provides a solid foundation for increased power output and engine longevity without compromising fitment or reliability.

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.
