Key Features:

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

• Forged from premium 2618 aluminum alloy for excellent strength and fatigue resistance under high stress.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and efficiency.
• Tool steel wrist pins provide superior durability and precise fitment for reliable piston-to-rod connection.
• Moly skirt coatings on select part numbers reduce friction and improve wear characteristics.
• 1.5cc dome design optimizes combustion chamber shape for improved power and efficiency.
• Precision machining ensures consistent dimensions and tight tolerances for optimal engine balance.
• Compatible with stock 99.5mm bore and stroke dimensions for direct fitment in Chrysler 5.7L HEMI engines.

Construction & Design:

The pistons are meticulously forged from 2618 aluminum alloy, known for its high strength and excellent thermal conductivity, which helps manage heat in high-performance applications. The cam and barrel skirt profiles have been extensively tested to minimize friction and piston slap, contributing to smoother engine operation and longer component life.

Each piston features a tool steel wrist pin that is engineered for maximum durability and precise alignment with the connecting rod. The moly skirt coating applied to select pistons further reduces friction between the piston and cylinder wall, enhancing wear resistance and improving overall engine efficiency.

Installation & Fitment:

This piston set is designed for direct replacement in Chrysler 5.7L HEMI engines with a 99.5mm bore and stock stroke. It fits applications requiring a -1.5cc dome piston to optimize compression and combustion characteristics. Installation requires standard engine assembly procedures and is best performed by experienced engine builders or technicians.
