Part #: 597400CE-8

Overview

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

Whether you are assembling a street performance build, a race motor, or a heavy-duty engine rebuild, these pistons provide superior combustion efficiency and long-lasting performance. Manley’s advanced forging and precision machining ensure consistent quality and optimal power delivery under demanding conditions.

Key Features

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

• Forged from premium 2618 aluminum alloy for excellent strength and fatigue resistance under high stress
• 9.3cc dome design optimizes combustion chamber shape for improved power and efficiency
• Proven cam and barrel skirt profiles reduce friction and piston slap, enhancing stability and longevity
• Tool steel wrist pins provide increased durability and precise fitment with connecting rods
• Moly skirt coatings on select pistons reduce friction and improve wear characteristics
• Precision CNC machining ensures tight tolerances and consistent performance across all pistons
• Maintains stock 3.917-inch stroke for compatibility with factory components
• Ideal for high-boost, forced induction, and high-RPM extreme duty builds

Construction & Design

These pistons are forged from 2618 aluminum alloy, a material favored in high-performance engines for its superior strength and thermal properties. The forging process enhances the 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 extending component life. Select pistons feature moly skirt coatings that further reduce wear and help maintain tight clearances over time.

Tool steel wrist pins ensure a robust and reliable connection between the piston and connecting rod, capable of withstanding high loads and stresses common in performance and extreme duty applications. The 9.3cc dome volume is carefully designed to optimize combustion chamber dynamics, contributing to efficient power delivery and throttle response.

Installation & Fitment

This piston set is a direct replacement for Chrysler 5.7L HEMI engines with a 90.9mm bore and stock 3.917-inch stroke. It fits a wide range of 2003 through 2024 Chrysler, Dodge, Jeep, and Ram models equipped with the 5.7L HEMI engine.

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