• Proven cam and barrel skirt profiles reduce friction and wear, enhancing piston stability and efficiency.
• Equipped with tool steel wrist pins for increased strength and longevity in connecting rod articulation.
• Moly skirt coatings on select part numbers reduce friction and improve piston ring seal for better performance.
• Designed with a -24cc dish volume to optimize combustion chamber shape and achieve a 9.09:1 compression ratio.
• Precision machining ensures consistent bore fitment and balanced weight for smooth engine operation.
• Compatible with Chrysler 6.1L HEMI engines featuring a 4.080-inch bore size.
• Trusted by professional engine builders and tuners for high-performance builds and durability.

Construction & Design:

The pistons are forged from 2618 aluminum alloy, known for its superior strength and thermal resistance compared to standard cast pistons. This material choice allows the pistons to endure high combustion pressures and temperatures common in performance and racing engines.

Manley’s design incorporates cam and barrel skirt profiles that minimize piston slap and reduce friction against the cylinder walls, contributing to smoother engine operation and longer component life. The tool steel wrist pins provide a robust connection between the piston and connecting rod, essential for high-RPM reliability.

The moly skirt coating applied on select pistons further reduces friction and wear, enhancing ring seal and overall engine efficiency. The -24cc dish design optimizes combustion chamber volume to achieve the specified compression ratio, balancing power output and engine safety.

Installation & Fitment:

This piston set is engineered for direct fitment in Chrysler 6.1L HEMI engines with a 4.080-inch bore. They are designed to meet or exceed OEM specifications, ensuring compatibility with factory components and clearances.

Installation should be performed by experienced engine builders or technicians familiar with high-performance engine assembly. Proper ring installation, clearances, and torque specifications must be followed to ensure optimal performance and durability.
