599910C-8

Overview:

The Manley Performance Platinum Series Dish Pistons are precision-engineered components designed specifically for the Dodge 6.4L HEMI engine with a 4.1-inch bore and +20.50cc dish volume. This set of eight pistons is built to deliver exceptional strength, durability, and performance for high-output and modified engines.

Ideal for professional engine builders, tuners, and enthusiasts seeking reliable, high-quality pistons, these components help support increased power levels while maintaining long-term engine integrity. Whether you are building a street performance engine or a track-focused powerplant, these pistons provide the foundation for enhanced combustion efficiency and durability.

Key Features:

Manley’s Platinum Series pistons incorporate advanced materials and design features to meet the demands of high-performance Dodge HEMI engines:

• Constructed from premium 2618 aluminum alloy forgings for superior strength and fatigue resistance under extreme conditions.
• Proven cam and barrel skirt profiles reduce friction and wear, improving piston stability and longevity.
• Equipped with tool steel wrist pins that offer enhanced durability and precise fitment.
• Moly skirt coatings on select part numbers reduce friction and improve piston ring seal.
• +20.50cc dish volume pistons optimize combustion chamber shape for improved power and efficiency.
• Designed to exacting tolerances to ensure consistent performance and reliable fitment in 4.1-inch bore applications.
• Set of eight pistons included, suitable for complete V8 engine builds or rebuilds.

Construction & Design:

These pistons are forged from 2618 aluminum alloy, a material known for its excellent strength-to-weight ratio and resistance to thermal fatigue. The forging process enhances grain structure, providing superior toughness compared to cast pistons. The cam and barrel skirt profiles have been optimized through extensive testing to reduce piston slap and improve oil retention, which contributes to quieter operation and longer service life.

The tool steel wrist pins are precision-machined for a secure connection between the piston and connecting rod, ensuring reliable power transfer under high RPM and load conditions. Additionally, the moly skirt coatings applied to select pistons reduce friction against the cylinder walls, enhancing efficiency and minimizing wear.

Installation & Fitment:

This piston set is engineered for direct fitment in Dodge 6.4L HEMI engines with a 4.1-inch bore and requires no modifications to the engine block or connecting rods. They are designed to work seamlessly with OEM and aftermarket components that match these specifications.

Professional installation is recommended to ensure proper ring end gap, piston-to-wall clearance, and overall engine assembly quality. No cutting, drilling, or special tuning is required to install these pistons when used within their intended application.
