Construction & Design:

The assembly features a forged 4340 steel crankshaft, renowned for its toughness and fatigue resistance, ensuring it withstands high RPM and torque loads. The connecting rods are also forged from 4340 steel and utilize an H-beam design, which provides superior strength and stability under extreme conditions. The pistons are crafted from forged aluminum, offering a lightweight yet durable solution that helps reduce reciprocating mass and improve engine response.

The piston design includes two valve reliefs and a dished crown with an 18cc volume, optimizing combustion efficiency and clearance for high-lift camshafts. The use of plasmamoly-coated piston rings enhances ring life and sealing capability, contributing to improved compression and reduced oil consumption. This assembly is balanced internally to maintain smooth engine operation, although it is not externally balanced.

Installation & Fitment:

This rotating assembly is engineered to fit a wide range of Chrysler, Dodge, Jeep, and Ram models equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat engines. It is designed for use with a 58-tooth reluctor wheel and a 1-piece rear main seal style, ensuring compatibility with many factory and aftermarket components.

Installation requires standard engine rebuild procedures and should be performed by experienced technicians or engine builders. Note that this kit does not include camshaft, lifters, timing components, gaskets, or oil pump, so these must be sourced separately. Proper balancing and assembly techniques are essential to maximize performance and reliability.
