Key Features:

Manley’s Extreme Duty Flat Top Pistons incorporate advanced engineering and premium materials to ensure top-tier performance and durability:

• Constructed from 2618 alloy forgings, known for excellent strength and thermal resistance in high-performance environments.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and longevity.
• Equipped with tool steel wrist pins for superior strength and fatigue resistance.
• Moly skirt coatings on select part numbers reduce friction and improve piston ring seal.
• Flat top design with a 1.5cc dish volume optimized for combustion efficiency and compression ratio control.
• Precision machined to exact tolerances for reliable fitment and consistent performance.
• Designed to handle extreme duty cycles, making them suitable for street performance, racing, and high-boost applications.

Construction & Design:

These pistons are forged from premium 2618 aluminum alloy, a material favored in motorsports for its excellent strength-to-weight ratio and resistance to thermal fatigue. The forging process ensures a dense, uniform grain structure that withstands high cylinder pressures and temperatures.

The cam and barrel skirt profiles have been refined through extensive testing to minimize piston slap and reduce friction, contributing to smoother engine operation and improved durability. The inclusion of tool steel wrist pins enhances the connection between the piston and connecting rod, providing reliable performance under high RPM and load conditions.

Additionally, the moly skirt coating applied to select pistons reduces wear and friction against the cylinder walls, promoting longer engine life and better efficiency.

Installation & Fitment:

This piston set is designed as a direct replacement for the Dodge 5.7L HEMI engine with a 3.922 inch bore. Precision manufacturing ensures proper fitment with factory components and clearances, supporting a straightforward installation process.

Engine builders should verify compatibility with their specific build parameters, including compression ratio and clearances, but no special modifications are typically required for proper installation.
