Key Features

Manley’s Platinum Series pistons incorporate advanced materials and precision engineering to meet the needs of high-output Chrysler 6.1L HEMI engines:

• Forged from premium 2618 aluminum alloy for superior strength and fatigue resistance
• Proven cam and barrel skirt profiles reduce friction and wear for smoother operation
• Tool steel wrist pins enhance strength and reliability under high stress
• Moly skirt coatings on select pistons minimize friction and improve piston-to-cylinder wall interaction
• 11.5cc dished piston design optimizes combustion chamber volume for precise compression control
• Precision machining ensures tight tolerances and consistent fitment for reliable assembly
• Built to withstand extreme duty cycles including high RPM and boosted conditions

Construction & Design

These pistons are forged from 2618 aluminum alloy, a material favored in high-performance engines for its toughness and ability to handle elevated temperatures. The forging process enhances the grain structure, resulting in greater strength and durability compared to cast pistons.

The cam and barrel skirt profiles are carefully engineered to reduce friction and wear, contributing to improved efficiency and longer service life. Tool steel wrist pins provide a robust connection between piston and connecting rod, critical for handling the stresses of aggressive driving and racing.

Moly skirt coatings applied on select pistons further reduce friction between the piston skirts and cylinder walls, helping to prevent scuffing and extend engine life. The -11.5cc dished piston design allows for precise control over compression ratios, supporting a variety of tuning goals.

Installation & Fitment

This piston set is designed for Chrysler HEMI 6.1L engines with a 4.080-inch bore and 3.579-inch stroke, covering 2005 through 2010 models of the Chrysler 300C, Dodge Challenger, Dodge Charger, Dodge Magnum, and Jeep Grand Cherokee SRT8. Installation requires standard engine assembly procedures and attention to detail to ensure optimal performance and reliability.

These pistons are compatible with existing engine components designed for this bore and stroke combination, making them an excellent choice for professional engine builders and experienced enthusiasts upgrading or rebuilding their engines for enhanced durability and power.
