Manley Performance Extreme Duty Dome Piston Set: Fits Most Dodge / Chrysler Models (2003-2015)

Manley Performance Extreme Duty Dome Piston Set

Chrysler 5.7L HEMI 90.9mm Bore, 3.917in Stroke

597400CE-8

Overview:

The Manley Performance Extreme Duty Dome Piston Set is engineered specifically for Chrysler 5.7L HEMI engines, featuring a 90.9mm bore and a 3.917-inch stroke. Designed for professional engine builders and serious enthusiasts, these pistons deliver exceptional strength and reliability for high-performance applications.

Whether you are building a street performance engine, a race motor, or a heavy-duty rebuild, these pistons provide the durability and precision needed to withstand extreme conditions. You’ll get improved combustion efficiency and long-lasting performance thanks to Manley’s advanced forging and design techniques.

Key Features:

Manley’s Extreme Duty Dome Pistons incorporate advanced materials and design elements to ensure superior performance and durability:

• Constructed from 2618 alloy forgings, known for excellent strength and fatigue resistance under high stress.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and longevity.
• Equipped with tool steel wrist pins for increased durability and precise fitment.
• Moly skirt coatings on select part numbers reduce friction and improve piston skirt wear characteristics.
• 9.3cc dome design optimizes combustion chamber shape for improved power and efficiency.
• Precision CNC machining ensures tight tolerances and consistent performance across all pistons.
• Designed to maintain stock stroke dimensions (3.917 inches) for compatibility with factory components.
• Ideal for extreme duty applications including high-boost, forced induction, and high-RPM builds.

Construction & Design:

These pistons are forged from premium 2618 aluminum alloy, a material favored in high-performance engines for its superior strength and thermal properties. The forging process enhances grain structure, resulting in pistons that resist cracking and deformation under extreme heat and pressure.

The cam and barrel skirt profiles have been refined through extensive testing to minimize friction and piston slap, improving engine smoothness and longevity. The addition of moly skirt coatings on select models further reduces wear and helps maintain tight clearances over time.

Tool steel wrist pins provide a robust connection between the piston and connecting rod, ensuring reliable operation even under high loads. The 9.3cc dome volume is designed to optimize combustion chamber dynamics, contributing to efficient power delivery and throttle response.

Installation & Fitment:

This piston set is designed as a direct replacement for Chrysler 5.7L HEMI engines with a 90.9mm bore and stock 3.917-inch stroke. It fits applications requiring a 9.3cc dome piston configuration for extreme duty use.

Installation requires standard engine assembly procedures and proper clearances. These pistons are compatible with factory rods and other stock components, making them suitable for rebuilds or performance upgrades without extensive modifications.
