Manley Performance Platinum Series Pistons

Chrysler 5.7L HEMI 90.9mm Bore, Stock Stroke 3.922in Bore -12cc Dish

PIST-3.922/1.220 CD/DISHED -12cc (SKU: 597105C-8)

Overview:

The Manley Performance Platinum Series Pistons are precision-engineered forged pistons designed specifically for Chrysler 5.7L HEMI engines with a 90.9mm bore and a stock stroke. These pistons feature a -12cc dish design, ideal for maintaining proper compression ratios in modified or rebuilt engines.

Built for professional engine builders, tuners, and serious enthusiasts, these pistons deliver exceptional strength and durability under demanding conditions. Whether you are upgrading your engine for improved performance or rebuilding for reliability, Manley’s Platinum Series offers a proven solution that supports high horsepower and torque applications.

With a focus on quality and performance, these pistons help ensure your engine runs smoothly and efficiently, providing a solid foundation for your build.

Key Features:

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

• Forged from premium 2618 aluminum alloy for superior strength and fatigue resistance.
• Proven cam and barrel skirt profiles reduce friction and wear for improved durability.
• Tool steel wrist pins provide enhanced strength and reliability under high loads.
• Moly skirt coatings on select part numbers reduce friction and improve piston-to-cylinder wall interaction.
• 12cc dished piston design maintains optimal compression for modified combustion chambers.
• Precision machining ensures exact bore and stroke compatibility for Chrysler 5.7L HEMI engines.
• Designed to withstand the rigors of high-performance street, track, and racing applications.

Construction & Design:

These pistons are crafted using a high-quality 2618 aluminum alloy forging process, known for its excellent strength-to-weight ratio and resistance to thermal fatigue. The cam and barrel skirt profiles have been extensively tested to optimize piston stability and reduce skirt wear, which contributes to longer engine life and consistent performance.

The inclusion of tool steel wrist pins enhances the connection between the piston and connecting rod, ensuring reliable operation even under high RPM and boost conditions. Additionally, the moly skirt coating on select pistons reduces friction against the cylinder walls, improving efficiency and reducing heat buildup.

The -12cc dish design is engineered to complement the combustion chamber shape of the Chrysler 5.7L HEMI, helping maintain proper compression ratios and combustion efficiency in rebuilt or modified engines.

Installation & Fitment:

These pistons are designed as direct replacements for Chrysler 5.7L HEMI engines with a 90.9mm bore and stock stroke dimensions. They fit standard bore sizes and maintain factory stroke specifications, making them suitable for rebuilds and performance upgrades without requiring modifications to the engine block or other components.

Installation should be performed by experienced engine builders or technicians familiar with forged piston assemblies and proper clearances. No special machining beyond standard bore sizing is typically required when using these pistons in compatible engines.
