597220CE-8

Overview:

Manley Performance's Extreme Duty Pistons are engineered specifically for Dodge HEMI engines with a 3.937-inch bore and 4.050-inch stroke. This set of eight pistons is designed to deliver exceptional strength and reliability under demanding conditions, making them ideal for high-performance builds and serious engine upgrades.

Whether you are a professional engine builder, tuner, or enthusiast looking to enhance your engine’s durability and power potential, these pistons provide a solid foundation for your build. They are crafted to withstand extreme stress and high RPMs, ensuring long-lasting performance in both street and race applications.

Key Features:

These pistons incorporate advanced materials and design features to optimize strength, durability, and efficiency:

• Forged from premium 2618 aluminum alloy, known for its superior strength and thermal resistance compared to standard alloys.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and longevity.
• Equipped with tool steel wrist pins for increased strength and durability in high-load conditions.
• Moly skirt coatings on select part numbers reduce friction and improve wear resistance.
• Flat top piston design with a -1.5cc dish volume, optimized for combustion efficiency and compression ratio tuning.
• Precision machining ensures consistent bore and stroke compatibility for reliable engine assembly.
• Designed to meet the rigorous demands of extreme duty applications, including racing and high-performance street use.

Construction & Design:

Manley’s Extreme Duty Pistons are crafted using 2618 alloy forgings, a high-strength aluminum alloy favored in motorsports for its excellent fatigue resistance and thermal properties. The pistons feature carefully engineered cam and barrel skirt profiles that minimize friction and improve piston stability within the cylinder bore. Tool steel wrist pins add robustness to the piston-pin connection, critical for handling high combustion pressures and RPMs.

The moly skirt coating applied to select pistons further reduces friction and wear, contributing to smoother operation and extended engine life. The flat top design with a slight dish volume (-1.5cc) allows for precise control over compression ratios, making these pistons adaptable to various tuning setups and fuel types.

Installation & Fitment:

This piston set is designed for direct fitment in Dodge HEMI engines with a 3.937-inch bore and 4.050-inch stroke. They are intended for professional installation by experienced engine builders or technicians familiar with high-performance engine assembly.

Proper machining and clearances must be observed during installation to ensure optimal performance and durability. These pistons are compatible with existing engine components designed for the specified bore and stroke dimensions.
