Key Features

Manley’s Platinum Extreme Duty Pistons incorporate advanced engineering and premium materials to ensure superior performance and longevity:

• Forged from 2618 aluminum alloy for outstanding strength and fatigue resistance under extreme combustion pressures.
• Precision-machined with tight tolerances for consistent fitment and reliable engine assembly.
• Optimized cam and barrel skirt profiles reduce friction and piston slap, enhancing stability and wear resistance.
• Equipped with tool steel wrist pins to provide a robust, durable connection between piston and connecting rod.
• Molybdenum skirt coatings on applicable pistons reduce friction and improve wear characteristics.
• -5cc dish piston design tailored to optimize combustion chamber volume and support custom compression tuning.
• Specifically designed for Chrysler 6.4L HEMI engines with a 4.090-inch bore and 1.210-inch compression distance.

Construction & Design

These pistons are crafted from premium 2618 aluminum alloy, a material renowned for its superior thermal resistance and strength compared to conventional alloys. The forging process enhances the grain structure, resulting in pistons capable of withstanding the high pressures and temperatures typical of performance and racing engines.

Manley’s meticulous design includes advanced skirt profiles that minimize piston slap and friction, contributing to smoother engine operation and extended component life. The tool steel wrist pins ensure a strong and durable piston-to-rod connection, capable of handling high RPM and heavy load conditions without deformation.

The molybdenum skirt coating applied to select pistons further reduces friction against the cylinder walls, decreasing wear and improving overall engine efficiency. The -5cc dish design allows precise control over combustion chamber volume, enabling fine-tuned compression ratios for optimized performance.

Installation & Fitment

This piston set is a direct fit for Chrysler 6.4L HEMI engines with a 4.090-inch bore, covering a wide range of 2011 through 2024 models including the Chrysler 300, Dodge Challenger, Charger, Durango, Jeep Grand Cherokee, Wrangler, Ram 2500, Ram 3500, and Jeep Grand Wagoneer. Proper machining and assembly practices are essential to ensure optimal performance and reliability.

No modifications to the engine block or connecting rods are typically required when installing these pistons, provided the engine is prepared to the specified bore size and clearances.
