Key Features

Manley’s Extreme Duty Dome Pistons incorporate advanced engineering and premium materials to meet the rigorous demands of high-performance 5.7L HEMI applications:

• Forged from premium 2618 aluminum alloy for superior strength and fatigue resistance under extreme conditions.
• Optimized cam and barrel skirt profiles reduce friction and piston slap, enhancing durability and quiet operation.
• Equipped with tool steel wrist pins for maximum strength and reliability in high-load, high-RPM environments.
• Moly skirt coatings on select pistons reduce friction and improve piston ring seal for better efficiency.
• -1.5cc dome volume designed to optimize compression ratio and combustion efficiency.
• Precision 99.5mm bore diameter with stock stroke compatibility ensures direct fitment without modifications.
• Manufactured to tight tolerances for consistent performance and reliable engine operation.

Construction & Design

These pistons are forged using Manley’s advanced process with 2618 aluminum alloy, known for its excellent strength-to-weight ratio and thermal stability. The cam and barrel skirt profiles have been extensively tested to minimize piston slap and wear, resulting in quieter operation and extended engine life.

Tool steel wrist pins provide superior durability to withstand the rigors of high RPM and heavy load conditions without failure. The moly skirt coating further reduces friction between the piston and cylinder wall, improving efficiency and reducing heat buildup during operation.

Installation & Fitment

This piston set is designed as a direct replacement for Chrysler 5.7L HEMI engines with a 99.5mm bore and stock stroke configuration. The -1.5cc dome volume supports compression tuning without requiring modifications to the engine block or connecting rods. Installation follows standard engine rebuild procedures and is recommended to be performed by a professional to ensure proper clearances and ring end gaps for optimal performance and longevity.
