Overview:

Manley Performance’s Platinum Series pistons are precision-engineered forged components designed specifically for the Chrysler 6.4L HEMI engine. This set of eight pistons features a 4.100-inch bore diameter and a 5cc dish volume, paired with a 4.050-inch stroke to optimize combustion chamber dynamics and engine efficiency.

Ideal for professional engine builders, tuners, and serious enthusiasts, these pistons deliver superior strength and durability under high-performance conditions. Whether you are building a high-output street engine or a track-focused powerplant, Manley’s Platinum Series pistons provide the reliability and performance needed to support increased horsepower and torque.

Key Features:

These pistons incorporate advanced materials and design elements to ensure long-lasting performance and compatibility with demanding applications:

• Constructed from 2618 aluminum alloy forgings, known for excellent strength and fatigue resistance at elevated temperatures.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and longevity.
• Equipped with tool steel wrist pins for superior strength and precise fitment.
• Molybdenum skirt coatings on select part numbers reduce friction and improve piston ring seal.
• 5cc dish piston design optimizes compression ratio and combustion efficiency for the 6.4L HEMI platform.
• Precision machining ensures exact bore and stroke dimensions for consistent engine balance and performance.
• Designed to withstand the rigors of high-performance and forced induction applications.

Construction & Design:

The Manley Platinum Series pistons are crafted from premium 2618 aluminum alloy forgings, a material choice favored in high-performance engines for its superior strength and thermal stability compared to standard alloys. The forging process enhances grain structure, resulting in pistons that resist cracking and deformation under extreme conditions.

The pistons feature carefully engineered cam and barrel skirt profiles that minimize friction against the cylinder walls, reducing wear and improving efficiency. Tool steel wrist pins provide a robust connection between the piston and connecting rod, ensuring durability during high-RPM operation. Additionally, the moly skirt coatings applied to select pistons further reduce friction and help maintain optimal ring seal, contributing to improved engine longevity and performance.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.4L HEMI engines requiring a 4.100-inch bore and 4.050-inch stroke configuration. Installation should be performed by experienced engine builders or technicians familiar with high-performance engine assembly to ensure proper clearances and ring end gaps.

No modifications to the engine block are typically required when using these pistons, but it is recommended to verify compatibility with your specific build and any accompanying components.
