Overview

The Manley Performance Platinum Series 4.100" Bore -5cc Dish .927" Pin Stroker Piston Set is engineered specifically for the Chrysler 6.4L 392 HEMI engine, covering model years 2011 through 2024. Designed for high-performance applications, this set of eight forged pistons features a 4.100-inch bore diameter combined with a 4.050-inch stroke, optimizing combustion efficiency and engine output. Ideal for professional engine builders, tuners, and serious enthusiasts, these pistons deliver exceptional strength and durability to support increased horsepower and torque demands.

Whether building a high-output street engine or a track-focused powerplant, Manley’s Platinum Series pistons provide the reliability and precision required to withstand the rigors of aggressive driving and forced induction setups.

Key Features

Manley’s Platinum Series pistons incorporate advanced materials and design elements to ensure long-lasting performance and compatibility with demanding Chrysler 6.4L HEMI applications:

• Forged from premium 2618 aluminum alloy for superior strength and fatigue resistance at elevated temperatures
• 5cc dish piston design optimizes compression ratio and combustion chamber dynamics
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and longevity
• Tool steel wrist pins provide robust strength and precise fitment for high-RPM durability
• Molybdenum skirt coatings on select pistons reduce friction and improve piston ring seal
• Precision machining ensures exact bore and stroke dimensions for consistent engine balance and performance
• Designed to withstand high-performance and forced induction applications without compromise

Construction & Design

The Manley Platinum Series pistons are crafted from 2618 aluminum alloy forgings, a material renowned in high-performance engine builds for its excellent strength and thermal stability compared to standard alloys. The forging process refines the grain structure, resulting in pistons that resist cracking and deformation under extreme operating conditions.

These pistons feature carefully engineered cam and barrel skirt profiles to minimize friction against cylinder walls, reducing wear and improving overall engine efficiency. The inclusion of tool steel wrist pins ensures a durable connection between piston and connecting rod, critical for high-RPM operation. Additionally, molybdenum skirt coatings applied to select pistons further reduce friction and help maintain optimal ring seal, contributing to enhanced engine longevity and performance.

Installation & Fitment

This piston set is a direct fit for Chrysler 6.4L 392 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. Typically, no modifications to the engine block are necessary when using these pistons, but verifying compatibility with your specific build and related components is recommended.
