Chrysler HEMI 6.4L (392) Stock Stroke +0.005in Oversize / 4.095in Bore
598905C-8
Overview:
The Manley Performance Platinum Series piston set is engineered specifically for Chrysler HEMI 6.4L engines with a stock stroke and a +0.005 inch oversize bore of 4.095 inches. These pistons are designed to deliver exceptional strength, durability, and performance for enthusiasts and professional engine builders alike.
Whether you are building a high-performance street engine or a race-ready powerplant, this piston set provides the reliability and precision needed to handle increased power levels while maintaining excellent engine efficiency and longevity.
With a -12.5cc dish design, these pistons help optimize combustion chamber volume and compression ratio, contributing to improved power output and combustion stability.
Key Features:
Manley’s Platinum Series pistons incorporate advanced materials and design features to ensure superior performance and durability:
Construction & Design:
The pistons feature a fully forged 2618 aluminum alloy construction, known for its excellent strength-to-weight ratio and ability to withstand high combustion pressures and temperatures. The cam and barrel skirt profiles have been extensively tested to minimize piston slap and reduce friction, contributing to smoother engine operation and longer component life.
Tool steel wrist pins provide a robust connection between the piston and connecting rod, ensuring durability under high RPM and load conditions. The moly skirt coating applied to select pistons further reduces friction during initial break-in and ongoing operation, enhancing overall engine efficiency.
The -12.5cc dish design allows for precise control of compression ratio and combustion chamber shape, which is critical for tuning performance engines that require optimized combustion dynamics.
Installation & Fitment:
This piston set is designed for Chrysler HEMI 6.4L engines with a stock stroke and a bore size of 4.095 inches, featuring a +0.005 inch oversize dimension. It is ideal for engine rebuilds or performance upgrades requiring precise bore sizing and piston volume adjustments.
Installation should be performed by experienced engine builders or technicians familiar with forged piston applications and proper engine assembly procedures. Ensure all clearances and specifications are verified during installation to maintain optimal engine performance and reliability.
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!
