Manley Performance Platinum Series Pistons

Chrysler 5.7L HEMI Stroker 3.922in Bore / 4.050in Stroke

PIST-3.922/1.085 CD/DISHED -14cc

Overview:

The Manley Performance Platinum Series Pistons are precision-engineered components designed specifically for Chrysler 5.7L HEMI stroker engines featuring a 3.922-inch bore and 4.050-inch stroke. Crafted for professional engine builders, tuners, and serious enthusiasts, these pistons deliver exceptional strength and reliability under demanding conditions.

Whether you are building a high-performance street machine or a race-ready engine, these pistons provide the durability and performance needed to maximize your engine’s potential. With advanced materials and proven design features, you’ll get consistent power delivery and long-lasting operation.

Key Features:

Manley’s Platinum Series Pistons incorporate advanced technology and materials to ensure superior performance and durability:

• Forged from premium 2618 aluminum alloy for excellent strength and fatigue resistance.
• Proven cam and barrel skirt profiles reduce friction and wear for improved efficiency.
• Equipped with tool steel wrist pins for enhanced durability and precise fitment.
• Moly skirt coatings on select part numbers reduce friction and improve piston ring seal.
• Designed with a dished piston crown providing a -14cc combustion chamber volume for optimized compression and combustion.
• Precision machining ensures tight tolerances and consistent performance across all pistons in the set.
• Ideal for stroked 5.7L HEMI applications requiring increased displacement and power output.

Construction & Design:

The Platinum Series Pistons are manufactured using a high-quality 2618 aluminum alloy forging process, which offers superior strength compared to standard hypereutectic pistons. This alloy maintains its integrity under high thermal and mechanical stress, making it ideal for performance and racing applications.

The pistons feature carefully engineered cam and barrel skirt profiles that minimize friction against the cylinder walls, enhancing efficiency and reducing wear. The inclusion of moly skirt coatings on select models further decreases friction and helps maintain ring seal, contributing to improved engine longevity and performance.

Tool steel wrist pins provide a robust connection between the piston and connecting rod, ensuring reliable operation even under high RPM and load conditions. The dished piston crown design helps control compression ratio, which is critical when building stroker engines to balance power and reliability.

Installation & Fitment:

These pistons are designed as direct replacements for Chrysler 5.7L HEMI stroker builds with a 3.922-inch bore and 4.050-inch stroke. They fit applications requiring a dished piston with a -14cc combustion chamber volume. Installation should be performed by experienced engine builders familiar with stroker engine assembly to ensure proper clearances and ring end gaps.

No special coatings or machining beyond standard stroker engine preparation are required. Proper balancing and ring fitting are recommended to achieve optimal performance and durability.
