- Fully balanced rotating assembly for smooth operation and reduced vibration
- Forged aluminum pistons with a dished design and two valve reliefs, featuring a +17cc piston head volume for improved combustion efficiency
- Forged 4340 steel crankshaft and connecting rods for superior strength and durability under high stress
- I-beam connecting rod design with a 6.125-inch center-to-center length for optimal rod geometry
- Plasmamoly piston ring facing material for enhanced wear resistance and sealing
- Stock size rod and main bearings included for precise fitment
- Floating wrist pins for reduced friction and reliable piston articulation
- Comprehensive kit including pistons, crankshaft, rods, bearings, and rings for a complete rotating assembly solution
Construction & Design:
SCAT’s rotating assemblies are crafted using premium forged materials to withstand the rigors of high-performance and forced induction applications. The crankshaft and connecting rods are forged from 4340 steel, known for its exceptional tensile strength and fatigue resistance. The pistons are forged aluminum, providing a lightweight yet durable component that helps reduce reciprocating mass and improve throttle response.
The pistons feature a dished crown with valve reliefs to ensure proper clearance and combustion chamber compatibility with modern Hemi and SRT engines. The use of plasmamoly piston rings enhances durability and sealing, contributing to consistent compression and oil control. Each assembly is internally balanced to factory specifications, ensuring smooth engine operation and longevity.
Installation & Fitment:
This rotating assembly is designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram 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 compatible with factory components such as harmonic balancers, flexplates, and flywheels, which are not included in this kit.
Professional installation is recommended to ensure proper clearances and torque specifications are met. This kit is ideal for engine builders looking to maintain OEM dimensions while upgrading to stronger forged internals.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
