Key Features

Manley’s Platinum Series pistons incorporate advanced materials and design elements to maximize performance and durability:

• Forged from high-strength 2618 aluminum alloy for superior fatigue resistance and toughness
• Proven cam and barrel skirt profiles reduce friction and improve piston stability within the cylinder
• Tool steel wrist pins offer enhanced strength and wear resistance for demanding applications
• Moly skirt coatings on select part numbers reduce friction and heat buildup under high loads
• Flat top piston design with a -1.5cc dish volume to optimize combustion chamber geometry and compression
• Precision machining ensures tight tolerances and consistent fitment for reliable engine assembly
• Engineered specifically for Dodge HEMI engines with 3.937-inch bore and 4.050-inch stroke configuration

Construction & Design

These pistons are forged from 2618 aluminum alloy, renowned for its excellent strength-to-weight ratio and ability to endure high thermal and mechanical stresses common in high-performance engines. The cam and barrel skirt profiles have been extensively tested to minimize piston slap and wear, promoting smoother engine operation and extended service life.

Each piston is equipped with a durable tool steel wrist pin, providing superior strength compared to standard pins. Additionally, the moly skirt coating applied to select pistons reduces friction between the piston skirt and cylinder wall, enhancing efficiency and reducing heat generation during operation.

Installation & Fitment

This piston set is designed specifically for Dodge 5.7L HEMI engines with a 3.937-inch bore and 4.050-inch stroke, ensuring precise fitment and proper clearance. The flat top pistons with a -1.5cc dish volume accommodate specific combustion chamber requirements without the need for engine block or connecting rod modifications in most cases.

Installation should be performed by a qualified engine builder or technician to guarantee correct assembly, clearances, and optimal engine performance.
