Chrysler 300C / Dodge Charger / Magnum 05-08 5.7L Hemi
597400C-8
Overview:
The Manley Performance Platinum Series piston set is engineered specifically for Chrysler 5.7L HEMI engines featuring a 3.917-inch bore and a 90.9mm stock stroke. These high-quality forged pistons are designed to deliver exceptional strength and durability for performance enthusiasts and professional engine builders alike.
Whether you are building a high-output street engine or a reliable race motor, this piston set provides the foundation for improved power and long-lasting reliability. The 9.3cc dome design optimizes combustion efficiency and compression characteristics tailored to the 5.7L HEMI platform.
Key Features:
Manley’s Platinum Series pistons incorporate advanced materials and design features to ensure superior performance and durability:
Construction & Design:
The pistons are crafted from 2618 alloy, a high-strength aluminum alloy known for its excellent thermal stability and fatigue resistance. This material choice allows the pistons to withstand the extreme temperatures and pressures found in high-performance HEMI engines.
Manley’s attention to detail is evident in the skirt design, which features cam and barrel profiles optimized to reduce friction and wear. The inclusion of moly skirt coatings on select models further enhances durability and reduces piston-to-cylinder wall friction.
Each piston is equipped with a tool steel wrist pin, ensuring a secure and durable connection to the connecting rod. The 9.3cc dome shape is engineered to improve combustion efficiency and support higher compression ratios, making these pistons ideal for performance builds.
Installation & Fitment:
This piston set is designed as a direct replacement for Chrysler 5.7L HEMI engines with a 3.917-inch bore and 90.9mm stock stroke. The pistons are precision-machined to OEM specifications, ensuring proper fitment without the need for modifications.
Installation requires standard engine assembly procedures. No special machining or tuning beyond typical rebuild practices is necessary when using these pistons in compatible engines.
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!
