Overview:

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

Whether you are upgrading your engine for street performance, racing, or custom tuning, these pistons provide the reliability and quality needed to support increased power and efficiency. With a 4.090-inch bore and a 3.579-inch stroke, they are optimized for balanced performance and engine longevity.

Key Features:

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

• Forged from 2618 aluminum alloy, known for its high strength and excellent fatigue resistance under extreme conditions.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and engine efficiency.
• Equipped with tool steel wrist pins for increased strength and reliability in high-stress applications.
• Moly skirt coatings on select part numbers reduce friction and improve piston ring seal for better performance.
• Designed with a -6.5cc dish to optimize combustion chamber volume and compression ratio for the 6.2L HEMI platform.
• Precision machining ensures consistent bore size and stroke compatibility for reliable engine assembly.
• Trusted by professional engine builders and tuners for high-performance and durability demands.

Construction & Design:

The pistons are crafted using a high-quality 2618 aluminum alloy forging process, which provides superior strength compared to standard cast pistons. This alloy offers excellent thermal conductivity and fatigue resistance, making it ideal for high-performance and forced induction engines.

The cam and barrel skirt profiles have been extensively tested and proven to reduce piston slap and wear, contributing to smoother engine operation and longer component life. The moly skirt coating further reduces friction between the piston and cylinder wall, enhancing efficiency and reducing heat buildup.

Tool steel wrist pins add another layer of durability, ensuring the pistons can withstand the high loads and stresses encountered in performance applications without failure.

Installation & Fitment:

These pistons are designed for direct fitment in Chrysler 6.2L HEMI engines with a 4.090-inch bore and 3.579-inch stroke. They are engineered to meet OEM specifications for seamless installation in compatible engine builds.

Installation should be performed by experienced engine builders or technicians familiar with high-performance engine assembly to ensure proper clearances and torque specifications are met.
