Manley Performance Chrysler 6.1L Hemi Stroker Series -11.5cc Dish Piston Set

Chrysler 6.1L HEMI Stroker Engines

597060C-8

Overview:

The Manley Performance Chrysler 6.1L Hemi Stroker Series piston set is engineered for enthusiasts and professional engine builders seeking reliable, high-performance components for their stroked HEMI engines. Designed specifically for 6.1L HEMI stroker builds, these pistons accommodate a 4.060-inch bore and feature a -11.5cc dish volume to optimize compression and combustion characteristics.

Built to withstand the rigors of high-output applications, this piston set delivers durability and precision fitment, ensuring your engine performs consistently under demanding conditions. Whether you are building a street, strip, or race engine, these pistons provide the strength and design features necessary to support increased power and reliability.

Key Features:

Manley’s Stroker Series pistons incorporate advanced materials and design elements to maximize performance and longevity:

• Constructed from 2618 aluminum alloy forgings known for superior strength and thermal resistance.
• Proven cam and barrel skirt profiles reduce friction and wear for enhanced durability.
• Tool steel wrist pins provide exceptional strength and resistance to bending or deformation.
• Moly skirt coatings on select part numbers reduce friction and improve piston-to-cylinder wall interaction.
• 11.5cc dish design optimizes combustion chamber volume for stroker engine configurations.
• Precision machining ensures tight tolerances and consistent performance across all pistons in the set.
• Compatible with 6.240-inch connecting rods and a 0.927-inch wrist pin diameter for proper fitment.

Construction & Design:

These pistons are crafted from high-grade 2618 aluminum alloy forgings, a material choice favored in high-performance and racing applications for its excellent strength-to-weight ratio and thermal stability. The forged construction provides superior resistance to cracking and deformation under extreme heat and pressure.

The cam and barrel skirt profiles have been refined through extensive testing to reduce piston slap and friction, contributing to smoother engine operation and longer component life. Additionally, the moly skirt coating on select pistons further minimizes wear and enhances lubrication between the piston and cylinder wall.

Each piston is precision-machined to exact specifications, ensuring optimal clearance and fitment with the specified 4.060-inch bore and 6.240-inch rod length. The -11.5cc dish volume is designed to complement the increased stroke of the 6.1L HEMI stroker, helping to maintain ideal compression ratios and combustion efficiency.

Installation & Fitment:

This piston set is designed specifically for Chrysler 6.1L HEMI stroker engine builds featuring a 4.060-inch bore and 6.240-inch connecting rods. Proper installation by a professional engine builder is recommended to ensure correct clearances and ring end gaps.

These pistons are intended to be used with compatible rods and wrist pins as specified. No modifications to the pistons themselves are required, but engine assembly should follow standard procedures for stroker builds.

What's Included:

• Complete set of forged 2618 aluminum pistons with -11.5cc dish volume
• Tool steel wrist pins sized at 0.927 inches
