Chrysler 6.4L HEMI 4.090in Bore / 3.724in Stroke 11:1 Compression Ratio
598800CE-8
Overview:
The Manley Performance Extreme Duty Piston Set is engineered specifically for Chrysler 6.4L HEMI engines, delivering reliable strength and precision for high-performance builds. Designed with professional engine builders and serious enthusiasts in mind, these pistons provide the durability and performance needed to handle demanding conditions and increased power levels.
Featuring a 1.75cc dome design and an 11:1 compression ratio, this piston set is ideal for those looking to optimize combustion efficiency and power output without sacrificing reliability. Whether you are building a street performance engine or a track-focused powerplant, these pistons offer a proven foundation for extreme duty applications.
Key Features:
Manley’s Platinum Series pistons incorporate advanced materials and design elements to ensure superior performance and longevity:
Construction & Design:
These pistons are crafted from 2618 alloy, a high-strength aluminum alloy known for its excellent thermal and mechanical properties in high-performance engines. The forging process ensures a dense, uniform grain structure that withstands the rigors of extreme combustion pressures and temperatures.
The cam and barrel skirt profiles have been carefully developed to minimize piston slap and reduce friction, contributing to smoother engine operation and longer component life. The inclusion of tool steel wrist pins further enhances the assembly’s durability, ensuring reliable piston-to-connecting rod articulation under heavy loads.
Additionally, the moly skirt coating applied to select pistons reduces metal-to-metal contact, lowering wear and improving break-in characteristics. The 1.75cc dome shape is optimized to work with the 11:1 compression ratio, balancing power gains with engine reliability.
Installation & Fitment:
This piston set is designed as a direct replacement for Chrysler 6.4L HEMI engines with a 4.090-inch bore and 3.724-inch stroke. It fits applications requiring an 11:1 compression ratio and a 1.75cc dome piston design. Installation requires standard engine assembly procedures and proper clearances to ensure optimal performance and longevity.
No modifications to the engine block or connecting rods are typically necessary when installing this piston set, but professional installation and precise machining are recommended to achieve the best results.
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!
