Key Features:

This piston set incorporates premium materials and design elements that make it a top choice for performance engine builds:

• Forged from 2618 aluminum alloy for outstanding strength and fatigue resistance under extreme conditions.
• Proven cam and barrel skirt profiles reduce friction and improve piston stability within the cylinder bore.
• Tool steel wrist pins provide enhanced durability and precise fitment for connecting rods.
• Moly skirt coatings on select part numbers reduce wear and improve piston ring seal.
• 1.75cc dome piston design optimizes combustion chamber volume for improved power and efficiency.
• Engineered for extreme duty applications, including high-boost and high-RPM environments.
• Compatible with Dodge 6.4L HEMI engines featuring a 4.100 inch bore size.

Construction & Design:

Manley’s Extreme Duty pistons are crafted using 2618 alloy, a premium forging material known for its toughness and ability to handle high thermal and mechanical stress. The pistons feature carefully developed cam and barrel skirt profiles that minimize piston slap and reduce 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 the increased loads typical in performance engines. Additionally, the moly skirt coating on select pistons further enhances wear resistance and reduces friction, helping to maintain optimal ring seal and engine efficiency over time.
