Key Features:

Manley’s Extreme Duty Pistons incorporate advanced engineering and materials to meet the needs of high-performance Chrysler 5.7L HEMI builds. Key features include:

• Forged from premium 2618 aluminum alloy for superior strength and fatigue resistance under extreme conditions.
• Proven cam and barrel skirt profiles that reduce friction and wear, enhancing piston stability and longevity.
• Tool steel wrist pins for increased durability and precise fitment, ensuring reliable piston-to-connecting rod connection.
• Moly skirt coatings on select part numbers to minimize friction and improve wear resistance.
• 12cc dished piston design to optimize combustion chamber volume and support desired compression ratios.
• Compatible with stock stroke crankshafts and 3.917-inch bore cylinders for direct fitment without modification.
• Set of eight pistons, providing a complete solution for V8 engine builds.

Construction & Design:

These pistons are crafted from 2618 alloy, a high-strength aluminum alloy known for its excellent thermal stability and toughness, making it a preferred choice for high-performance and racing applications. The forging process ensures a dense, uniform grain structure that enhances durability and resistance to cracking under high loads.

The cam and barrel skirt profiles have been refined through extensive testing to reduce piston slap and improve ring seal, contributing to smoother engine operation and longer component life. Tool steel wrist pins provide a robust connection point that resists deformation and wear, critical for maintaining precise piston movement.

The moly skirt coating applied on select pistons reduces friction between the piston skirts and cylinder walls, which helps lower wear and improve efficiency. The -12cc dish design balances compression requirements with clearance needs, making these pistons suitable for a variety of performance builds.

Installation & Fitment:

This piston set is designed for Chrysler 5.7L HEMI engines with a stock stroke and a 3.917-inch bore, ensuring direct compatibility with factory cylinder dimensions. Installation requires standard engine assembly procedures and is intended for professional or experienced builders familiar with high-performance engine components.

No modifications to the engine block or crankshaft are necessary when using these pistons, provided the engine matches the specified bore and stroke. Proper ring installation and clearance checks are recommended to ensure optimal performance and reliability.

What's Included:

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

Ideal For:
