Featuring a -23cc dish design, these pistons optimize combustion chamber volume for precise tuning and improved efficiency, making them ideal for performance upgrades, racing builds, and heavy-duty stroker configurations. Whether you are increasing boost levels or building a reliable, long-lasting engine, Manley Extreme Duty Pistons provide the foundation for maximizing power and engine longevity.

Key Features

Manley’s Extreme Duty Pistons incorporate advanced engineering and premium materials to ensure superior performance and durability in demanding environments:

• Forged from high-strength 2618 aluminum alloy for excellent fatigue resistance and thermal stability under extreme conditions.
• Precision cam and barrel skirt profiles reduce friction and piston slap, enhancing ring seal and extending component life.
• Tool steel wrist pins provide a robust, precise connection between piston and connecting rod for reliable operation at high RPMs.
• Moly skirt coatings on select pistons reduce friction and wear, improving efficiency and cylinder wall protection.
• -23cc dished piston design optimizes compression ratio and combustion efficiency for performance tuning flexibility.
• Designed as a direct fit for Chrysler 5.7L HEMI engines with 3.917-inch bore and 4.050-inch stroke dimensions.
• Complete set of eight pistons included, suitable for full V8 engine builds or rebuilds.
• Trusted by professional engine builders and tuners for consistent quality and reliability in extreme duty applications.

Construction & Design

These pistons are manufactured using Manley’s renowned "Platinum Series" forging process, utilizing premium 2618 aluminum alloy known for its superior strength-to-weight ratio and excellent thermal stability. The cam and barrel skirt profiles have been extensively tested to minimize piston slap and improve ring seal, resulting in smoother engine operation and longer-lasting components.

The inclusion of tool steel wrist pins ensures a durable and precise piston-to-connecting rod interface capable of handling high RPM and heavy load conditions. Additionally, the moly skirt coating on select pistons reduces friction between the piston skirts and cylinder walls, minimizing wear and enhancing overall engine efficiency.

Installation & Fitment

This piston set is designed as a direct replacement for Chrysler 5.7L HEMI engines with a 3.917-inch bore and 4.050-inch stroke, covering a wide range of vehicles from 2003 to 2024. Installation requires standard engine assembly procedures, including precise machining and clearancing to ensure proper fitment and optimal performance.

No major modifications to the engine block are typically necessary beyond standard rebuild practices, making these pistons ideal for custom builds, stroker applications, and high-performance rebuilds where durability and strength are critical.
