Manley Performance Extreme Duty Pistons

Chrysler 5.7L HEMI Stock Stroke 3.937in Bore

597120CE-8

Overview:

Manley Performance's Extreme Duty Pistons are engineered specifically for Chrysler 5.7L HEMI engines with a stock stroke and a 3.937-inch bore. This set of eight pistons is designed to deliver exceptional strength and reliability for high-performance applications, making them an ideal choice for professional engine builders, tuners, and enthusiasts seeking durable, race-ready components.

Constructed from premium 2618 alloy forgings, these pistons provide superior fatigue resistance and thermal stability compared to standard cast pistons. Whether you are building a high-output street engine or a track-focused powerplant, these pistons offer the durability and precision needed to withstand extreme conditions while maintaining optimal performance.

Key Features:

Manley’s Extreme Duty Pistons incorporate advanced design and materials to ensure long-lasting performance and reliability:

• Forged from high-strength 2618 aluminum alloy for excellent durability and heat resistance.
• Proven cam and barrel skirt profiles reduce friction and wear for improved efficiency and longevity.
• Tool steel wrist pins provide enhanced strength and resistance to bending or deformation under high loads.
• Moly skirt coatings on select part numbers reduce friction and improve piston-to-cylinder wall interaction.
• 12cc dish design optimizes combustion chamber volume for improved compression and performance tuning.
• Precision machining ensures consistent bore sizing and tight tolerances for reliable fitment and sealing.
• Designed to maintain stock stroke and bore dimensions, allowing for straightforward installation in compatible engines.

Construction & Design:

These pistons are crafted using Manley’s signature "Platinum Series" forging process, which emphasizes material integrity and dimensional accuracy. The 2618 alloy used is known for its superior strength at elevated temperatures, making it well-suited for high-performance and extreme-duty applications.

The cam and barrel skirt profiles have been extensively tested to reduce piston slap and wear, contributing to quieter operation and longer engine life. Additionally, the tool steel wrist pins offer a robust connection between the piston and connecting rod, capable of handling increased power and RPM demands.

The -12cc dish design helps optimize combustion chamber shape and compression ratio, which can be beneficial for various tuning setups and forced induction applications.

Installation & Fitment:

This piston set is designed for Chrysler 5.7L HEMI engines with a stock stroke and a 3.937-inch bore, making it a direct fit for compatible builds without the need for extensive modifications. The pistons maintain OEM bore sizing and stroke, facilitating a straightforward installation process when combined with appropriate rings and hardware.

Professional installation is recommended to ensure proper clearances and ring end gaps. No cutting, drilling, or special tuning is required solely due to piston installation, but engine tuning should be adjusted as needed to match the new piston specifications.
