Overview:

The Manley Chrysler 6.1L Hemi Stroker Series -11.5cc Dish Piston Set is engineered for enthusiasts and professional engine builders seeking enhanced performance and durability in their high-output HEMI stroker builds. These pistons are designed to deliver reliable strength and precision fitment, making them ideal for both street and track applications where increased displacement and power are desired.

Crafted from premium materials and featuring advanced design elements, this piston set supports improved combustion efficiency and engine longevity. Whether you are upgrading your existing 6.1L HEMI or building a stroker engine from the ground up, these pistons provide the foundation for a robust and high-performing powerplant.

Key Features:

Manley’s Stroker Series pistons incorporate proven technology and materials to ensure superior performance and durability:

• Forged from 2618 aluminum alloy, known for its excellent strength and fatigue resistance under high-stress conditions.
• Proven cam and barrel skirt profiles that reduce friction and wear, enhancing piston stability and longevity.
• Tool steel wrist pins for maximum strength and durability in demanding applications.
• Moly skirt coatings on select part numbers to minimize friction and improve piston ring seal.
• 11.5cc dish design to optimize combustion chamber volume and compression ratio for stroker engines.
• Precision manufacturing ensures consistent dimensions and weight for balanced engine operation.
• Compatible with Chrysler 6.1L HEMI stroker configurations, supporting increased displacement and power output.

Construction & Design:

These pistons are meticulously crafted using 2618 alloy forgings, a material favored in high-performance applications for its superior strength and thermal resistance compared to standard aluminum alloys. The forged construction allows the pistons to withstand the increased pressures and temperatures typical of stroker engines.

The cam and barrel skirt profiles have been refined through extensive testing to reduce piston slap and friction, contributing to smoother engine operation and improved durability. The inclusion of tool steel wrist pins further enhances the pistons’ ability to endure high loads without deformation.

Additionally, the moly skirt coatings applied to select pistons reduce wear and friction between the piston skirts and cylinder walls, promoting longer service life and consistent performance.

Installation & Fitment:

This piston set is designed specifically for Chrysler 6.1L HEMI stroker engines, ensuring precise fitment and compatibility. Installation requires standard engine assembly procedures and should be performed by experienced technicians or engine builders familiar with stroker configurations.

Proper ring installation, clearances, and torque specifications must be observed to maximize performance and reliability. No modifications to the pistons are necessary, as they are engineered for direct use in compatible stroker builds.

What's Included:

• Complete set of forged 2618 alloy pistons with -11.5cc dish design
• Tool steel wrist pins
• Pre-applied moly skirt coatings on select pistons
