Chrysler 5.7L HEMI V8 – 3.937in Bore / 3.579in Stroke

597520C-8

Overview:

The Manley Performance Platinum Series Piston Set is engineered specifically for Chrysler 5.7L HEMI engines, featuring a precise 3.937-inch bore and 3.579-inch stroke configuration. Designed for professional engine builders and serious enthusiasts alike, these pistons deliver exceptional strength and durability to support high-performance builds and demanding driving conditions.

Whether you are upgrading your engine for street performance, track use, or heavy-duty applications, this piston set provides the reliability and precision needed to maximize your engine’s potential. With a +1.50cc flat top design, these pistons help optimize combustion chamber volume for improved efficiency and power delivery.

Key Features:

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

• Forged from premium 2618 aluminum alloy for outstanding strength and fatigue resistance under high stress.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and engine efficiency.
• Equipped with tool steel wrist pins for increased durability and precise fitment.
• Moly skirt coatings on select part numbers minimize friction and improve piston skirt lubrication.
• +1.50cc flat top piston design optimizes combustion chamber volume for enhanced power and throttle response.
• Precision machining ensures consistent bore sizing and tight tolerances for reliable engine assembly.
• Trusted by professional engine builders and tuners for high-performance and racing applications.

Construction & Design:

These pistons are crafted using 2618 alloy, a high-strength aluminum alloy known for its excellent thermal stability and resistance to cracking under extreme conditions. The forged construction provides superior toughness compared to cast pistons, making them ideal for boosted, high-RPM, or otherwise demanding engine builds.

The cam and barrel skirt profiles have been carefully engineered to reduce piston slap and improve ring seal, contributing to smoother operation and longer engine life. Tool steel wrist pins offer a robust connection between the piston and connecting rod, ensuring reliable performance even under high loads.

Additionally, the moly skirt coating on select models reduces friction between the piston skirt and cylinder wall, helping to lower wear and improve efficiency during break-in and throughout the engine’s lifespan.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 5.7L HEMI engines with a 3.937-inch bore and 3.579-inch stroke. It is intended for professional installation by experienced engine builders or mechanics familiar with high-performance engine assembly.

Proper machining and clearancing of the cylinder bore and related components are required to ensure optimal fitment and performance. No additional modifications to the engine block are typically necessary beyond standard rebuild procedures.
