597080C-8

Overview:

The Manley Performance Platinum Series Piston Set is engineered specifically for the Chrysler HEMI 6.1L engine featuring a 4.080-inch bore and 3.579-inch stroke. Designed for professional engine builders and serious enthusiasts, these pistons deliver exceptional strength, durability, and performance for high-output applications.

Whether you are building a high-performance street engine or a race-ready powerplant, this piston set provides the reliability and precision needed to handle increased cylinder pressures and aggressive tuning. You’ll get a proven design that supports improved combustion efficiency and long-term engine durability.

Key Features:

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

• 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 while maintaining tight piston-to-wall clearance.
• Tool steel wrist pins provide enhanced durability and resistance to bending or deformation.
• Molybdenum skirt coatings on select part numbers reduce friction and improve piston ring seal.
• 11.5cc dish design optimizes combustion chamber volume for precise compression ratio control.
• Manufactured to exacting tolerances for consistent fitment and performance in the 6.1L HEMI platform.
• Ideal for high-performance builds requiring reliable pistons capable of handling increased boost, nitrous, or high RPM operation.

Construction & Design:

The pistons are crafted from 2618 alloy, a high-strength aluminum alloy known for its excellent thermal fatigue resistance and toughness in demanding engine environments. The forged construction ensures a dense, uniform grain structure that withstands extreme combustion pressures and temperatures.

Manley’s attention to detail is evident in the cam and barrel skirt profiles, which are optimized to reduce piston slap and friction without sacrificing durability. The tool steel wrist pins add strength where it’s most needed, while the moly skirt coatings on select pistons further enhance wear resistance and reduce friction against the cylinder walls.

The -11.5cc dished piston crown is designed to complement the 6.1L HEMI’s combustion chamber geometry, helping to achieve the desired compression ratio and promote efficient combustion.

Installation & Fitment:

This piston set is engineered as a direct replacement for Chrysler HEMI 6.1L engines with a 4.080-inch bore and 3.579-inch stroke. It is compatible with stock and aftermarket components designed for this displacement and bore size.

Professional installation is recommended to ensure proper ring end gap, piston-to-wall clearance, and wrist pin fitment. No modifications to the engine block are typically required when using this piston set, making it suitable for rebuilds and performance upgrades alike.

What's Included:

• Complete set of forged 2618 alloy pistons with -11.5cc dish design
