Manley Performance Platinum Series Extreme Pistons

Chrysler 6.1L HEMI 4.065in Bore, 1.085in Compression Dome -24cc Stroker

598765CE-8

Overview:

The Manley Performance Platinum Series Extreme Pistons are precision-engineered forged pistons designed specifically for Chrysler 6.1L HEMI engines with a 4.065-inch bore and 1.085-inch compression dome. This set of eight pistons is ideal for enthusiasts and professional engine builders seeking enhanced durability and performance in stroker engine builds.

Constructed from high-strength 2618 alloy forgings, these pistons offer exceptional resistance to heat and stress, making them well suited for high-performance street, track, and racing applications. Whether you are upgrading your engine for increased power or building a reliable stroker setup, these pistons provide the strength and reliability needed to handle elevated cylinder pressures and RPMs.

With proven cam and barrel skirt profiles, tool steel wrist pins, and molybdenum skirt coatings on select part numbers, Manley’s Platinum Series pistons deliver reduced friction and improved wear characteristics, helping your engine run smoother and last longer under demanding conditions.

Key Features:

These pistons incorporate advanced design and materials to maximize performance and durability:

• Forged from premium 2618 aluminum alloy for superior strength and thermal resistance
• Proven cam and barrel skirt profiles reduce friction and improve piston stability
• Tool steel wrist pins provide enhanced durability and precise fitment
• Molybdenum skirt coatings on select pistons reduce wear and scuffing
• Dished piston design with a -24cc volume to optimize compression ratio for stroker applications
• Precision machined for exact bore and dome dimensions (4.065in bore, 1.085in compression dome)
• Designed to withstand the rigors of high-performance and extreme duty cycles
• Compatible with Chrysler 6.1L HEMI stroker engine builds requiring reliable, high-quality pistons

Construction & Design:

Manley’s Platinum Series pistons are crafted from 2618 alloy, a premium forging material known for its excellent strength-to-weight ratio and resistance to thermal fatigue. The pistons feature carefully engineered cam and barrel skirt profiles that minimize piston slap and friction, contributing to smoother engine operation and longer component life.

The inclusion of tool steel wrist pins ensures a robust connection between the piston and connecting rod, capable of handling high loads without deformation. Additionally, the moly skirt coatings applied to select pistons reduce friction against the cylinder walls, improving efficiency and wear resistance.

The dished piston design with a -24cc volume is optimized for stroker engine configurations, helping to achieve the desired compression ratio while maintaining combustion efficiency and power output.

Installation & Fitment:

This piston set is engineered for direct fitment in Chrysler 6.1L HEMI engines with a 4.065-inch bore and 1.085-inch compression dome specifications. They are ideal for stroker builds requiring a -24cc dished piston design.

Installation should be performed by experienced engine builders or technicians familiar with high-performance engine assembly to ensure proper clearances and torque specifications are met. These pistons are designed to integrate seamlessly with compatible rods and rings for a complete stroker setup.
