Manley Performance Platinum Series Pistons

Chrysler 5.7L HEMI V8 Stock Stroke 3.917in Bore

597100C-8

Overview:

The Manley Performance Platinum Series Pistons are precision-engineered forged pistons designed specifically for Chrysler 5.7L HEMI engines with a stock stroke and a 3.917-inch bore. This set of eight pistons features a -12cc dish design, optimized for combustion efficiency and compatibility with stock stroke configurations.

Ideal for performance enthusiasts, professional engine builders, and tuners, these pistons deliver superior strength and durability to support high-performance builds and extended engine life. Whether you are upgrading your engine for street performance, track use, or demanding applications, Manley’s Platinum Series pistons provide reliable, consistent results.

Key Features:

Manley’s Platinum Series Pistons incorporate advanced materials and design features to ensure optimal performance and longevity:

• Constructed from high-quality 2618 aluminum alloy forgings for exceptional strength and fatigue resistance under high stress.
• Proven cam and barrel skirt profiles that reduce friction and improve piston stability within the cylinder bore.
• Tool steel wrist pins engineered for maximum durability and precise fitment.
• Molybdenum (moly) skirt coatings on select part numbers to minimize wear and reduce friction for smoother operation.
• 12cc dished piston crown design to optimize combustion chamber volume and support desired compression ratios.
• Set of eight pistons, perfectly matched for balanced engine performance and smooth operation.
• Designed to maintain stock stroke dimensions with a 3.917-inch bore size for direct fitment in compatible Chrysler 5.7L HEMI engines.

Construction & Design:

Each piston in the Platinum Series is meticulously forged from 2618 aluminum alloy, a material known for its excellent strength-to-weight ratio and resistance to thermal fatigue. The forging process ensures a dense, uniform grain structure that withstands the rigors of high-performance combustion environments.

The pistons feature carefully engineered cam and barrel skirt profiles that reduce piston slap and friction, enhancing engine smoothness and efficiency. The inclusion of tool steel wrist pins provides a robust connection between the piston and connecting rod, capable of handling increased loads without deformation.

Additionally, the moly skirt coating applied to select pistons reduces wear and friction between the piston skirt and cylinder wall, contributing to longer engine life and improved performance consistency.

Installation & Fitment:

This piston set is designed for Chrysler 5.7L HEMI engines with a stock stroke and a 3.917-inch bore, making it a direct replacement for factory pistons in compatible applications. The -12cc dish design allows for proper combustion chamber volume and compression ratio adjustments without requiring modifications to the engine block or cylinder heads.

Installation should be performed by a qualified engine builder or technician familiar with high-performance engine assembly. These pistons are intended to fit within OEM specifications and do not require custom machining or special tuning beyond standard rebuild procedures.

What's Included:

• Set of 8 forged 2618 aluminum alloy pistons with -12cc dish design
• Tool steel wrist pins matched to each piston
• Pre-applied moly skirt coatings on select pistons

Ideal For:

• Performance enthusiasts upgrading Chrysler 5.7L HEMI engines for increased durability and power potential
• Professional engine builders seeking reliable, high-quality forged pistons for custom builds
• Street and track applications requiring pistons capable of handling elevated cylinder pressures and temperatures
• Rebuilds where maintaining stock stroke and bore dimensions is critical

Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
