Manley Performance Extreme Duty Dish Pistons

2003–2024 Chrysler 5.7L HEMI Applications

Part #: 597120CE-8

Overview

Manley Performance Extreme Duty Dish Pistons are precision-engineered for Chrysler 5.7L HEMI engines with a stock stroke of 3.937 inches and bore size of 3.937 inches. This set of eight forged pistons is built to deliver exceptional strength, durability, and reliability for high-performance and extreme-duty applications. Ideal for professional engine builders, tuners, and enthusiasts, these pistons provide the robust construction needed to withstand the rigors of high-output street builds and demanding track environments.

Designed to maintain OEM bore and stroke dimensions, these pistons offer a direct fit solution that simplifies installation while enhancing engine longevity and performance. Whether upgrading a daily driver or building a race-ready powerplant, Manley’s Extreme Duty Pistons ensure consistent, dependable operation under elevated stress and temperature conditions.

Key Features

Manley’s Extreme Duty Pistons incorporate advanced materials and design elements to maximize performance and durability:

• Forged from premium 2618 aluminum alloy for superior strength and thermal resistance.
• Optimized cam and barrel skirt profiles reduce friction and piston slap for quieter, longer-lasting operation.
• Tool steel wrist pins provide enhanced strength and resistance to bending under high load conditions.
• Moly skirt coatings on select pistons reduce friction and improve piston-to-cylinder wall interaction.
• 12cc dish design optimizes combustion chamber volume for improved compression and tuning flexibility.
• Precision machining ensures consistent bore sizing and tight tolerances for reliable fitment and sealing.
• Maintains stock stroke and bore dimensions for straightforward installation without extensive modifications.

Construction & Design

These pistons are manufactured using Manley’s renowned "Platinum Series" forging process, emphasizing material integrity and dimensional accuracy. The 2618 aluminum alloy is chosen for its excellent fatigue resistance and strength retention at elevated temperatures, making it ideal for high-performance and extreme-duty engine builds.

The cam and barrel skirt profiles have been extensively tested to minimize piston slap and wear, contributing to quieter operation and extended engine life. The inclusion of tool steel wrist pins ensures a robust connection between the piston and connecting rod, capable of handling increased power output and high RPM demands.

The -12cc dish design is engineered to optimize combustion chamber shape and compression ratio, supporting a wide range of tuning setups including naturally aspirated and forced induction applications.

Installation & Fitment

This piston set is designed specifically for Chrysler 5.7L HEMI engines from 2003 through 2024, including models such as the Chrysler 300 and 300C, Dodge Challenger, Charger, Dakota, Durango, Magnum, Ram trucks, Jeep Commander, Grand Cherokee, and Wagoneer. The pistons maintain OEM bore and stroke dimensions, allowing for a direct fit installation in compatible engines without the need for cutting, drilling, or special machining.

Professional installation is recommended to ensure proper clearances and ring end gaps. While no modifications are required solely due to piston installation, engine tuning should be adjusted to match the new piston specifications for optimal performance and reliability.
