Chrysler HEMI 6.4L (392) 4.095in Bore / 3.724in Stroke
598805C-8
Overview:
The Manley Performance Platinum Series Pistons are precision-engineered forged pistons designed specifically for the Chrysler 6.4L HEMI engine. Crafted to exacting standards, these pistons deliver outstanding strength and durability for high-performance builds. Whether you are a professional engine builder or a serious enthusiast, these pistons provide the reliability and performance needed to handle increased power and demanding conditions.
Built to withstand the rigors of street, strip, or track applications, these pistons help optimize combustion efficiency and engine response. The 1.75cc dome design supports higher compression ratios, enhancing power output while maintaining excellent durability. With Manley’s reputation for quality, you can trust these pistons to perform consistently in your Chrysler HEMI 6.4L build.
Key Features:
Manley’s Platinum Series Pistons incorporate advanced materials and design features to ensure superior performance and longevity:
Construction & Design:
The Platinum Series Pistons are manufactured using a high-quality 2618 aluminum alloy forging process, which provides superior strength compared to cast pistons. This alloy is well known for its ability to withstand high thermal and mechanical stresses common in performance engines. The pistons feature carefully engineered cam and barrel skirt profiles that minimize friction and improve piston stability within the cylinder bore.
Tool steel wrist pins ensure a secure and durable connection between the piston and connecting rod, while the moly skirt coatings on select models reduce wear and improve piston ring seal. The dome shape of the piston crown is optimized for efficient combustion chamber dynamics, supporting higher compression ratios without compromising reliability.
Installation & Fitment:
These pistons are designed as direct replacements for the Chrysler 6.4L HEMI engine, matching the factory bore and stroke dimensions. They fit standard cylinder bores with a 4.095-inch diameter and a 3.724-inch stroke, making them suitable for rebuilds or performance upgrades on compatible engines.
Installation requires standard engine assembly procedures. No special modifications to the engine block or components are necessary beyond typical machining and fitting practices. These pistons are intended for use by experienced engine builders and require proper balancing and ring installation to ensure optimal performance.
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!
