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:
- Forged from premium 2618 aluminum alloy for exceptional strength and fatigue resistance.
- Proven cam and barrel skirt profiles to optimize piston stability and reduce friction.
- Tool steel wrist pins engineered for maximum durability and precise fitment.
- Moly skirt coatings on select part numbers to minimize wear and improve piston-to-cylinder wall interaction.
- 20.5cc dish volume designed to complement combustion chamber geometry for optimal compression and performance.
- Precision machining ensures consistent bore and stroke compatibility for the 6.4L HEMI engine platform.
- Coated piston surfaces enhance heat resistance and reduce carbon buildup.
- Set of eight pistons included to fully equip your V8 engine build.
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.
