• Forged aluminum flat-top pistons with two valve reliefs and +4.20cc piston head volume for improved combustion efficiency
• Plasmamoly piston rings designed for excellent sealing and wear resistance
• Balanced internal rotating assembly for smooth operation and reduced vibration
• Oversized pistons and rings at 0.035 inches (0.889 mm) for precise bore fitment
• Floating wrist pins for reliable piston articulation
• Includes rod and main bearings at stock undersize dimensions for ease of installation
• Designed for use with a 32-tooth reluctor wheel, ensuring compatibility with factory ignition systems

Construction & Design:

The Eagle Competition Rotating Assemblies Kit is constructed using premium forged materials to withstand the rigors of high-performance applications. The crankshaft and connecting rods are crafted from forged 4340 steel, known for its exceptional tensile strength and fatigue resistance, ensuring durability under extreme loads. The pistons are made from forged aluminum, providing a lightweight yet strong component that helps reduce reciprocating mass and improve throttle response.

Each piston features a flat-top design with two valve reliefs to optimize combustion chamber shape and clearance. The piston rings utilize plasmamoly facing material, which offers enhanced wear resistance and sealing capabilities, contributing to improved engine efficiency and longevity. The entire assembly is internally balanced to minimize vibrations and promote smooth engine operation at high RPMs.

Installation & Fitment:

This rotating assembly kit is designed as a direct fit for Chrysler, Dodge, Jeep, and Ram engines equipped with the 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. Installation requires standard engine assembly procedures and is intended for professional or experienced engine builders. Note that the kit does not include components such as the harmonic balancer, flexplate, flywheel, camshaft, lifters, timing chain and gears, gaskets, oil pump, or assembly lubricant, which must be sourced separately.

Compatibility is optimized for engines utilizing a 32-tooth reluctor wheel. Proper balancing and clearances should be verified during assembly to ensure peak performance and reliability.

What's Included:

• Forged 4340 steel crankshaft
• Forged 4340 steel H-beam connecting rods (6.125-inch length)
• Forged aluminum flat-top pistons with valve reliefs (+4.20cc volume)
• Plasmamoly piston rings (0.035-inch oversize)
• Rod bearings (stock undersize)
• Main bearings (stock undersize)

Ideal For:

This rotating assembly kit is ideal for performance enthusiasts, engine builders, and professional racers who demand a durable, high-quality rotating assembly for their Chrysler, Dodge, Jeep, or Ram Hemi engines.
