Manley Performance Stroker Series Extreme Duty Piston Set

Chrysler 6.4L HEMI 4.100 Bore

599910CE-8

Overview:

The Manley Chrysler 6.4L HEMI Stroker Series Extreme Duty Piston Set is engineered for serious performance enthusiasts and professional engine builders seeking reliable, high-strength components for their builds. Designed specifically for the 6.4L HEMI engine with a 4.100-inch bore, these pistons provide the durability and precision required to handle increased power and demanding conditions.

Featuring Manley’s signature Platinum Series technology, this piston set offers exceptional strength and wear resistance, making it ideal for high-performance street, track, or racing applications. Whether you’re upgrading your engine for more displacement or building a stroker motor, these pistons deliver consistent performance and long-term reliability.

Key Features:

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

• Constructed from 2618 alloy forgings, known for superior strength and fatigue resistance under extreme conditions.
• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and longevity.
• Equipped with tool steel wrist pins for maximum strength and durability in high-stress environments.
• Moly skirt coatings on select part numbers reduce friction and improve break-in characteristics.
• 20.5cc dish design optimizes combustion chamber volume for stroker engine builds.
• Precision machined to exacting tolerances for consistent bore fit and performance.
• Designed to withstand the increased loads and stresses of extreme duty applications.

Construction & Design:

The pistons are forged from premium 2618 aluminum alloy, a material favored in high-performance engine components for its excellent strength-to-weight ratio and resistance to thermal fatigue. The forged construction ensures superior toughness compared to cast pistons, making them well-suited for stroker engines and boosted applications.

Manley’s attention to detail is evident in the cam and barrel skirt profiles, which are optimized to reduce piston slap and improve oil control. The tool steel wrist pins provide a robust connection between the piston and connecting rod, capable of handling high RPM and increased cylinder pressures. Additionally, the moly skirt coating on select pistons reduces friction during operation, contributing to smoother performance and extended component life.

Installation & Fitment:

This piston set is designed specifically for Chrysler 6.4L HEMI engines with a 4.100-inch bore, making it a direct fit for stroker builds requiring a -20.5cc dish piston. Installation requires standard engine assembly procedures and precise measurements to ensure proper ring end gaps and clearances.

These pistons are intended for professional engine builders or experienced enthusiasts familiar with high-performance engine assembly. No modifications to the block bore are necessary beyond standard honing and sizing to 4.100 inches.
