This set of eight forged pistons is designed to provide exceptional strength and durability for high-performance and extreme duty applications. Whether you are a professional engine builder, tuner, or enthusiast, these pistons offer a reliable foundation to enhance engine longevity and power potential under demanding conditions.

Built to withstand high combustion pressures and elevated RPMs, these pistons are ideal for serious engine upgrades, racing, and high-performance street use. Their precise design and premium materials ensure consistent performance and durability in both daily driving and competitive environments.

Key Features

Manley’s Extreme Duty Pistons incorporate advanced engineering and materials to optimize strength, efficiency, and wear resistance:

• Forged from premium 2618 aluminum alloy for superior strength and thermal resistance compared to standard alloys
• Cam and barrel skirt profiles reduce friction and wear, improving piston stability and longevity
• Tool steel wrist pins provide enhanced strength and durability under high-load conditions
• Moly skirt coatings on select pistons reduce friction and improve wear resistance for smoother operation
• Flat top piston design with a -1.5cc dish volume, optimized for combustion efficiency and compression ratio tuning
• Precision machining ensures exact bore and stroke compatibility for reliable engine assembly
• Designed to meet the rigorous demands of racing and extreme duty applications

Construction & Design

These pistons are crafted from 2618 alloy forgings, a high-strength aluminum alloy widely used in motorsports for its excellent fatigue resistance and thermal properties. The cam and barrel skirt profiles are engineered to minimize friction and enhance piston stability within the cylinder bore, reducing wear and improving overall engine efficiency.

Tool steel wrist pins reinforce the piston-pin connection, critical for handling the high combustion pressures and RPMs typical of performance engines. Additionally, the moly skirt coating applied to select pistons further reduces friction and wear, contributing to extended engine life and smoother operation.

The flat top design with a slight -1.5cc dish volume 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 5.7L HEMI engines with a 3.937-inch bore and 4.050-inch stroke, covering a wide range of Chrysler, Dodge, Jeep, and Ram models from 2003 to 2024. Installation should be performed by experienced engine builders or technicians familiar with high-performance engine assembly.

Proper machining and clearance specifications 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, making them an excellent upgrade for both rebuilds and performance enhancements.
