Construction & Design:

The Eagle Competition Rotating Assembly Kit is built with premium materials to ensure maximum strength and longevity under high-stress conditions. The forged 4340 steel crankshaft and connecting rods provide exceptional toughness and resistance to fatigue, essential for performance applications. The forged aluminum pistons are designed with flat tops and valve reliefs to optimize combustion chamber dynamics while maintaining durability.

The plasmamoly piston rings offer superior wear resistance and sealing capabilities, contributing to improved compression and reduced oil consumption. The assembly is designed for use with a 3.927-inch (99.746 mm) bore and a 4.050-inch stroke, matching the specifications of many popular Hemi engines. This kit’s components are engineered to work harmoniously, ensuring reliable operation and longevity.

Installation & Fitment:

This rotating assembly kit is designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines, including the 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk models. Installation requires standard engine rebuild procedures and is intended for professional or experienced enthusiasts familiar with engine assembly.

Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so those must be sourced separately. It is designed for use with a 32-tooth reluctor wheel and a 1-piece rear main seal style. Proper balancing and clearances should be verified during installation to ensure optimal performance and reliability.
