• Designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition systems

Construction & Design:

The Eagle Competition Rotating Assemblies Kit is built with premium materials and precision engineering to withstand the stresses of high-performance applications. The forged 4340 steel crankshaft and connecting rods provide exceptional tensile strength and fatigue resistance, essential for handling increased horsepower and torque. The forged aluminum pistons are lightweight yet durable, featuring a dished design with valve reliefs to maintain proper clearance and combustion chamber volume.

All components are manufactured to tight tolerances to ensure optimal balance and fitment, although this kit is not internally balanced. The plasmamoly piston rings offer excellent sealing and wear characteristics, contributing to improved engine efficiency and longevity. This kit does not include camshaft, lifters, or timing components, allowing builders to customize their engine setup according to specific performance goals.

Installation & Fitment:

This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. Installation requires standard engine assembly procedures and compatibility with a 32-tooth reluctor wheel setup. Additional components such as harmonic balancer, flexplate, flywheel, camshaft, lifters, timing chain, gears, gaskets, and oil pump are not included and must be sourced separately.

Professional installation is recommended to ensure proper clearances, torque specifications, and engine balance. This kit is ideal for engine builders who want to upgrade or rebuild their Hemi engines with high-quality rotating components.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
• Forged aluminum pistons with two valve reliefs and +26.50cc volume
• Plasmamoly piston rings (0.015" oversize)
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This kit is perfect for performance enthusiasts, engine builders, and professional shops looking to assemble or rebuild Chrysler, Dodge, Jeep, or Ram Hemi engines with enhanced durability and strength.
