597900C-8

Overview:

The Manley Performance Platinum Series Pistons are precision-engineered forged pistons designed specifically for Chrysler 6.2L HEMI engines. Crafted to meet the demands of professional engine builders and performance enthusiasts alike, these pistons deliver exceptional strength, durability, and reliability under high-stress conditions.

Whether you are building a high-performance street engine or a race-ready powerplant, these pistons provide the foundation for enhanced power and efficiency. Their carefully optimized design supports improved combustion and engine response, helping you get the most out of your 6.2L HEMI build.

Key Features:

Manley’s Platinum Series Pistons incorporate advanced materials and design features to ensure superior performance and longevity:

• Constructed from 2618 aluminum alloy forgings, known for excellent strength and fatigue resistance in high-performance applications.
• Proven cam and barrel skirt profiles reduce friction and wear, contributing to smoother operation and extended piston life.
• Equipped with tool steel wrist pins for enhanced durability and precise fitment.
• Moly skirt coatings on select part numbers reduce friction and improve piston skirt lubrication.
• 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 configuration, matching factory and performance build specifications.
• Manufactured to tight tolerances to ensure consistent performance and reliable fitment.

Construction & Design:

These pistons are forged from premium 2618 aluminum alloy, a material favored in motorsports for its superior strength and thermal properties compared to standard cast pistons. The forging process enhances grain structure, providing resistance to cracking and deformation under extreme heat and pressure.

The skirt design incorporates cam and barrel profiles that reduce piston slap and friction, improving engine smoothness and efficiency. Tool steel wrist pins offer robust connection points between the piston and connecting rod, ensuring durability during high-RPM operation.

The moly skirt coating applied to select pistons further reduces friction and wear, contributing to longer engine life and improved performance consistency.

Installation & Fitment:

These pistons are designed as direct replacements for Chrysler 6.2L HEMI engines with a 4.090-inch bore and 3.579-inch stroke. They fit applications requiring a -6.5cc dish piston design to maintain proper combustion chamber volume.

Installation requires standard engine assembly procedures. No special modifications or machining beyond typical honing and clearance checks are necessary when used within compatible engine builds.
