231003927

Overview:

The Eagle Competition Rotating Assemblies 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. Designed to support engine displacements up to 6.4L/392 cubic inches, this kit provides the essential forged components needed to build a durable and performance-capable powerplant. Whether you are rebuilding a street engine or assembling a race-ready motor, this kit offers a solid foundation with premium materials and precision manufacturing.

Ideal for those upgrading or refreshing their Hemi engines, the kit focuses on core rotating parts, ensuring strength and durability under demanding conditions. It is perfect for builds that require forged internals without the inclusion of ancillary components like camshafts or oil pumps, allowing for customization and flexibility in engine assembly.

Key Features:

This rotating assembly kit combines quality materials and thoughtful design to deliver dependable performance:

• Forged 4340 steel crankshaft for exceptional strength and durability
• Forged 4340 steel H-beam connecting rods with a 6.125-inch center-to-center length for optimal balance of strength and weight
• Forged aluminum pistons featuring a dome design without valve reliefs, optimized for high compression and performance
• Pistons and rings oversized by 0.010 inches to accommodate bore refinishing and ensure a tight seal
• Plasmamoly piston ring facing material for enhanced wear resistance and sealing capability
• Floating wrist pins for reduced friction and improved durability
• Complete set of rod and main bearings included at stock undersizes for precise fitment
• Includes piston rings to complete the sealing system
• Rear main seal style: 1-piece for simplified installation and reliable sealing

Construction & Design:

The Eagle Competition Rotating Assemblies 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, a material known for its superior tensile strength and fatigue resistance, ensuring longevity even under high RPM and load conditions. The H-beam design of the rods provides an excellent strength-to-weight ratio, reducing reciprocating mass while maintaining structural integrity.

Forged aluminum pistons are designed with a dome shape to support higher compression ratios, enhancing combustion efficiency and power output. The absence of valve reliefs in the piston crown allows for maximum strength and durability. The use of plasmamoly-coated piston rings improves ring life and sealing performance, critical for maintaining compression and minimizing blow-by in demanding environments.

Installation & Fitment:

This kit is designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines, including 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 models. Installation requires standard engine assembly procedures and precision machining to ensure proper clearances and fitment. Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately to complete the engine build. Professional installation is recommended to achieve optimal results and engine reliability.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Forged aluminum dome pistons (0.010" oversize)
• Piston rings with plasmamoly facing
• Rod bearings (stock undersize)
• Main bearings (stock undersize)
• Floating wrist pins

Ideal For:

• Engine builders upgrading or rebuilding Chrysler/Dodge/Jeep/Ram Hemi engines
• Performance enthusiasts seeking durable forged rotating assemblies for street or race applications
• Custom engine builds requiring high-strength forged internals without additional components
• Rebuild projects aiming to restore or improve engine reliability and power potential

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.
