Part #: 597320CE-8

Overview

The Manley Stroker Series Pistons are precision-forged components engineered specifically for Chrysler 5.7L HEMI engines from 2003 through 2024. Designed to meet the demands of stroker builds and high-performance upgrades, these pistons deliver exceptional strength and durability for both street and race applications. Whether you are an enthusiast building a powerful street engine or a professional engine builder assembling a high-output race motor, these pistons offer reliable performance and enhanced engine longevity under increased cylinder pressures.

Crafted by Manley Performance, a trusted name in the automotive industry, these pistons ensure consistent quality and are optimized to improve combustion efficiency and withstand the rigors of extreme duty use.

Key Features

Manley’s Stroker Series Pistons incorporate advanced materials and design elements that provide superior strength, durability, and efficiency for Chrysler 5.7L HEMI stroker applications:

• Forged from premium 2618 aluminum alloy for excellent strength and fatigue resistance under high stress and elevated temperatures.
• 3.937-inch bore diameter and 1.085-inch compression height tailored to fit Chrysler 5.7L HEMI stroker engine builds.
• -14cc dished crown design optimizes combustion chamber shape for improved detonation resistance and tuning flexibility.
• Extended dome (E/D) configuration supports increased compression ratios and enhanced performance tuning.
• Proven cam and barrel skirt profiles reduce friction and piston slap, improving ring seal and piston stability.
• Tool steel wrist pins provide superior durability and precise fitment for a reliable piston-to-rod connection under high RPM and load.
• Moly skirt coatings on select pistons reduce friction during break-in and throughout service life, enhancing longevity.
• Set of 8 pistons included, ideal for complete V8 engine builds.

Construction & Design

Manufactured using Manley’s signature "Platinum Series" forging process, these pistons feature 2618 aluminum alloy known for its excellent strength-to-weight ratio and thermal conductivity. This alloy is ideal for high-performance engines that operate under elevated temperatures and pressures, ensuring durability and resistance to fatigue.

The pistons’ cam and barrel skirt profiles are engineered to minimize piston slap and reduce wear, contributing to smoother engine operation and improved ring sealing. The moly skirt coating further decreases friction during initial break-in and helps maintain low friction throughout the piston’s lifespan.

The -14cc dished crown design allows for precise control over combustion chamber volume, making these pistons compatible with a variety of cylinder head designs and compression ratios. Tool steel wrist pins ensure a robust and reliable connection to the connecting rods, capable of handling the stresses of high-performance and stroker engine builds.

Installation & Fitment

These pistons are designed as direct replacements for Chrysler 5.7L HEMI stroker engines requiring a 3.937-inch bore and 1.085-inch compression height with a -14cc dish piston specification. They fit a wide range of Chrysler, Dodge, Jeep, and Ram models equipped with the 5.7L HEMI engine from 2003 to 2024.

Installation should be performed by experienced engine builders or technicians familiar with precision engine assembly. Proper ring fitting, piston-to-cylinder clearances, and engine balancing are essential to achieve optimal performance and durability.
