Key Features:

This rotating assembly kit combines quality materials and precision engineering to enhance engine reliability 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
• H-beam forged 4340 steel connecting rods with 6.125-inch center-to-center length for enhanced rigidity
• Plasmamoly piston rings included, sized at 0.020-inch oversize for improved sealing and wear resistance
• Complete set of rod and main bearings at stock undersize for precise fitment
• Floating wrist pins for reduced friction and reliable piston articulation
• Engine displacement of 6.5L (394 cubic inches) with a bore of 3.937 inches and stroke of 4.050 inches
• Designed for use with a 1-piece rear main seal style
• Balanced assembly not included, allowing customization based on specific build requirements

Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with premium materials to withstand the rigors of high-performance applications. The forged 4340 steel crankshaft and connecting rods provide exceptional tensile strength and fatigue resistance, essential for engines subjected to increased power and RPMs. The forged aluminum pistons feature a dome shape with valve reliefs, optimizing combustion chamber dynamics and clearance for high-lift camshafts.

Plasmamoly piston rings enhance durability and maintain optimal sealing under extreme conditions, reducing blow-by and oil consumption. The kit’s components are precision machined to tight tolerances, ensuring proper fit and smooth operation within the engine block.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including performance variants such as the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk. Installation requires professional engine assembly knowledge and proper machining of the engine block to accommodate the 0.020-inch oversize pistons and rings.

Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately. It is designed for use with a 58-tooth reluctor wheel and a 1-piece rear main seal style. Balancing is not included, allowing builders to tailor the assembly balance to their specific application.

What's Included:

• Forged 4340 steel crankshaft
