Manley Performance Chrysler 6.1L Hemi 4.080in Bore Stroker Series -11.5cc Dish Piston Set Extreme Duty

Chrysler 6.1L HEMI V8 Stroker Engine

598680CE-8

Overview:

The Manley Performance Stroker Series piston set is engineered specifically for Chrysler 6.1L HEMI stroker engines with a 4.080-inch bore. Designed for extreme duty applications, these pistons offer enhanced strength and durability to withstand the rigors of high-performance and racing environments. Whether you are building a powerful street machine or a track-focused build, this piston set delivers reliable performance and longevity.

Crafted from premium 2618 alloy forgings, these pistons provide superior resistance to heat and fatigue compared to standard cast pistons. The -11.5cc dish design optimizes combustion chamber volume for improved compression and efficiency in stroked configurations. If you demand robust components that professional engine builders trust, this Manley piston set is an ideal choice.

Key Features:

Manley’s Stroker Series pistons incorporate advanced design and materials to ensure maximum performance and durability:

• Constructed from high-strength 2618 aluminum alloy forgings for excellent thermal and mechanical resistance.
• Proven cam and barrel skirt profiles reduce friction and wear for improved piston stability and longevity.
• Tool steel wrist pins provide superior strength and durability under extreme loads.
• Moly skirt coatings on select part numbers reduce friction and improve break-in characteristics.
• 11.5cc dish piston design optimizes combustion chamber volume for stroker engine applications.
• Precision machining ensures tight tolerances and consistent fitment for reliable engine assembly.
• Extreme duty rating suitable for high-boost, high-RPM, and racing applications.

Construction & Design:

These pistons are meticulously crafted using 2618 alloy, a premium aerospace-grade aluminum known for its superior strength and heat resistance. The forging process enhances grain structure, resulting in pistons that can endure the high cylinder pressures and temperatures typical of stroked HEMI engines. The cam and barrel skirt profiles have been optimized to reduce piston slap and improve oil retention, contributing to smoother operation and extended engine life.

Additionally, the tool steel wrist pins offer exceptional durability, preventing deformation under extreme stress. The moly skirt coating applied to select pistons reduces friction during initial break-in and ongoing operation, minimizing wear and enhancing overall engine efficiency.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.1L HEMI stroker builds with a 4.080-inch bore. Precision manufacturing ensures compatibility with corresponding engine components, facilitating a straightforward installation process. As with all high-performance engine parts, professional assembly and proper clearances are recommended to achieve optimal results.

• Designed for 6.1L HEMI stroker engines with 4.080-inch bore diameter.
• Compatible with standard wrist pin sizes and ring end gaps for this application.
• No modifications to the block or connecting rods are typically required.
