Chrysler HEMI 6.4L (392) - 4.095 Inch Bore, 6.125 Inch Rod, 4.05 Inch Stroke
599905C-8
Overview:
Manley Performance’s Platinum Series pistons are precision-engineered forged pistons designed specifically for the Chrysler 6.4L HEMI engine. This set of eight pistons features a 4.095 inch bore diameter, paired with 6.125 inch connecting rods and a 4.05 inch stroke, making it an ideal upgrade for builders seeking enhanced durability and performance in their 392 HEMI builds.
These pistons are crafted for professional engine builders, tuners, and serious enthusiasts who demand reliable strength and consistent performance under high-stress conditions. Whether you are building a high-horsepower street machine, a track-focused race engine, or a robust performance upgrade, these pistons provide the foundation for improved power and longevity.
With advanced materials and coatings, you’ll get superior wear resistance and reduced friction, helping your engine run smoother and last longer even under demanding use.
Key Features:
The Manley Platinum Series pistons incorporate advanced design and materials to deliver outstanding performance and durability:
Construction & Design:
Each piston in this set is forged from 2618 aluminum alloy, known for its superior strength and ability to withstand high combustion pressures and temperatures common in performance engines. The cam and barrel skirt profiles have been extensively tested to reduce piston slap and improve ring seal, contributing to longer engine life and smoother operation.
The tool steel wrist pins provide a robust connection between the piston and connecting rod, ensuring reliable performance even under extreme loads. Additionally, the moly skirt coating applied to these pistons reduces friction and wear, helping to maintain tight clearances and improve overall engine efficiency.
The 20.5cc dish design balances compression ratio and combustion characteristics, making these pistons well-suited for a variety of forced induction or naturally aspirated builds on the 6.4L HEMI platform.
Installation & Fitment:
This piston set is designed as a direct replacement for the Chrysler 6.4L HEMI engine with a 4.095 inch bore, 6.125 inch rod length, and 4.05 inch stroke. Proper machining and professional installation are recommended to ensure optimal fitment and performance.
These pistons are intended for engine builders familiar with high-performance assembly procedures. No modifications to the block or rods are typically required when using these pistons within their specified dimensions.
What's Included:
Ideal For:
Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
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!
