PIST-4.090/1.120CD/5ccDISH E/D (SKU: 599800CE-8)

Overview:

The Manley Platinum Extreme Series Pistons are precision-engineered forged pistons designed specifically for the Chrysler 6.4L HEMI engine with a 4.090-inch bore. This set of eight pistons features a -5cc dish design, optimized for high-performance builds requiring reliable durability and enhanced combustion efficiency.

Ideal for professional engine builders, tuners, and serious enthusiasts, these pistons deliver superior strength and longevity under demanding conditions. Whether you are building a high-output street engine or a race-ready powerplant, Manley’s Platinum Series pistons provide the performance and reliability you need to maximize your engine’s potential.

Key Features:

Manley’s Platinum Extreme Series Pistons incorporate advanced materials and design features to ensure exceptional performance and durability:

• Constructed from 2618 alloy forgings, known for excellent strength and fatigue resistance in high-stress environments.
• Proven cam and barrel skirt profiles reduce friction and wear, improving piston stability and longevity.
• Equipped with tool steel wrist pins for enhanced strength and durability at the piston-to-rod connection.
• Moly skirt coatings on select part numbers reduce friction and improve wear characteristics.
• 5cc dish piston design optimizes combustion chamber volume for improved compression and performance tuning.
• Precision machining ensures tight tolerances and consistent fitment for reliable engine assembly.
• Designed specifically for Chrysler 6.4L HEMI engines with a 4.090-inch bore and 1.210 compression distance.

Construction & Design:

The pistons are forged from premium 2618 aluminum alloy, a material favored in high-performance applications for its superior strength and thermal resistance compared to standard alloys. The forging process enhances grain structure, resulting in pistons that withstand extreme combustion pressures and temperatures.

Manley’s attention to detail includes optimized skirt profiles that reduce piston slap and friction, contributing to smoother engine operation and longer component life. The tool steel wrist pins provide a robust connection to the connecting rods, capable of handling high RPM and load conditions without deformation.

The molybdenum skirt coating applied on select pistons further reduces friction between the piston and cylinder wall, minimizing wear and improving efficiency. The -5cc dish design allows for precise control over compression ratio and combustion chamber shape, supporting custom engine builds and tuning strategies.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.4L HEMI engines with a 4.090-inch bore, making it suitable for rebuilds and performance upgrades where exact bore size and compression distance are required. Proper machining and assembly practices should be followed to ensure optimal performance and reliability.

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