Key Features:

These pistons incorporate advanced materials and design features to ensure optimal performance and durability:

• Forged from premium 2618 aluminum alloy for superior strength and fatigue resistance.
• Proven cam and barrel skirt profiles reduce friction and wear for smoother operation.
• Tool steel wrist pins provide enhanced durability and precise fitment.
• Moly skirt coatings on select part numbers minimize friction and improve piston ring seal.
• Dome-shaped piston design optimized for combustion efficiency and compression ratio control.
• Precision machining to exact bore size of 99.619mm ensures perfect fit and performance.
• Compatible with stock stroke of 3.579 inches for proper engine geometry.

Construction & Design:

Manley’s Platinum Series pistons are crafted using state-of-the-art forging techniques with 2618 alloy, known for its excellent strength-to-weight ratio and thermal stability. The cam and barrel skirt profiles have been extensively tested to reduce piston slap and improve ring seal, enhancing overall engine smoothness and efficiency.

The use of tool steel wrist pins adds toughness to the critical connection between piston and connecting rod, ensuring long-lasting durability even under high RPM and load conditions. Additionally, the moly skirt coating on select pistons reduces friction between the piston and cylinder wall, contributing to reduced wear and improved oil control.
