• Equipped with tool steel wrist pins for superior strength and precise fitment.
• Moly skirt coatings on select part numbers reduce friction and improve piston-to-cylinder wall interaction.
• 23cc dished piston design optimizes combustion chamber volume for targeted compression ratios.
• Precision machining ensures consistent bore diameter of 3.937 inches and reliable fitment.
• Compatible with high-performance Dodge 5.7L HEMI applications requiring durable forged pistons.

Construction & Design:

These pistons are meticulously forged from 2618 aluminum alloy, known for its high strength and excellent thermal properties, making it ideal for performance engines subjected to elevated temperatures and pressures. The cam and barrel skirt profiles have been extensively tested to reduce friction and wear, contributing to longer engine life and smoother operation.

The inclusion of tool steel wrist pins enhances the connection between piston and connecting rod, ensuring precise articulation and resistance to deformation. The moly skirt coating applied on select pistons further reduces friction against cylinder walls, improving efficiency and minimizing wear during extended use.
