Part #: 597900C-8

Overview

The Manley Performance Platinum Series Pistons are high-quality forged pistons engineered specifically for Chrysler’s 6.2L HEMI engines found in Hellcat, Trackhawk, and TRX models from 2015 through 2026. Designed for professional engine builders and serious performance enthusiasts, these pistons offer outstanding strength and durability to withstand the extreme conditions of high-performance and racing applications.

Whether you are assembling a powerful street engine or a race-ready build, these pistons provide a solid foundation for improved combustion efficiency, enhanced power delivery, and reliable operation under high stress. Their precision design ensures optimal fitment and performance in demanding Chrysler 6.2L HEMI configurations.

Key Features

Manley’s Platinum Series Pistons incorporate advanced engineering and premium materials to deliver superior performance and longevity:

• Forged from 2618 aluminum alloy, known for exceptional strength and fatigue resistance in high-heat, high-pressure environments.
• Cam and barrel skirt profiles reduce friction and piston slap, promoting smoother engine operation and extended piston life.
• Equipped with durable tool steel wrist pins for precise fitment and enhanced reliability at high RPMs.
• Moly skirt coatings on select pistons reduce friction and improve lubrication between piston and cylinder walls.
• Designed with a -6.5cc dish to optimize combustion chamber volume and compression ratio for the 6.2L HEMI engine.
• Compatible with a 4.090-inch bore and 3.579-inch stroke, matching factory and performance build specifications.
• Manufactured to tight tolerances for consistent performance and reliable installation.

Construction & Design

These pistons are forged from premium 2618 aluminum alloy, a material favored in motorsports for its superior strength, thermal conductivity, and resistance to cracking compared to standard cast pistons. The forging process refines the grain structure, enhancing durability under extreme heat and pressure conditions typical of high-performance engines.

The skirt design features cam and barrel profiles that minimize piston slap and reduce friction, contributing to smoother engine operation and improved efficiency. Tool steel wrist pins provide a robust connection between the piston and connecting rod, ensuring durability during aggressive driving and high-RPM use. Additionally, the moly skirt coating applied to select pistons further reduces wear and friction, extending engine life and maintaining consistent performance.

Installation & Fitment

Manley Platinum Series Pistons are designed as direct replacements for Chrysler 6.2L HEMI engines with a 4.090-inch bore and 3.579-inch stroke. The -6.5cc dish piston design maintains proper combustion chamber volume and compression ratio for optimal engine performance.

Installation follows standard engine assembly procedures. No special modifications or machining beyond typical cylinder honing and clearance checks are required when used within compatible engine builds, making these pistons an excellent choice for both OEM rebuilds and performance upgrades.
