Key Features

Manley’s Platinum Extreme Duty pistons incorporate advanced materials and design innovations to ensure superior performance and durability:

• Forged from premium 2618 aluminum alloy for outstanding strength and fatigue resistance under high stress.
• Optimized cam and barrel skirt profiles reduce friction and wear, enhancing efficiency and piston longevity.
• Tool steel wrist pins provide reinforced strength and durability in the piston-pin connection.
• Molybdenum skirt coatings on select pistons reduce friction and improve piston ring sealing.
• 1.220-inch compression height engineered for precise piston-to-cylinder fitment and optimal performance.
• 11.5cc dished crown volume tailored to specific combustion chamber requirements and compression ratios.
• Precision machining with tight tolerances ensures consistent fit and reliable operation.
• Designed specifically for Chrysler HEMI 6.1L engines requiring a 4.060-inch bore piston.

Construction & Design

The Manley Platinum Series pistons are crafted from high-grade 2618 forged aluminum alloy, a material favored in high-performance engine builds for its superior strength and thermal stability. The forging process refines the grain structure, resulting in pistons that resist cracking and deformation even under extreme heat and pressure.

Manley’s meticulous engineering is evident in the cam and barrel skirt profiles, which minimize friction and wear during operation. The moly skirt coating further reduces friction between the piston skirts and cylinder walls, promoting smoother engine operation and lowering heat generation. Each piston features a carefully designed dished crown with an 11.5cc volume to achieve the desired compression ratio and combustion characteristics for the 6.1L HEMI engine. Tool steel wrist pins add strength to the piston-pin assembly, ensuring durability during high-RPM and high-load conditions.

Installation & Fitment

This piston set is a direct fit replacement for Chrysler HEMI 6.1L engines with a 4.060-inch bore, compatible with 2005–2010 Chrysler 300C SRT8, Dodge Challenger SRT8, Dodge Charger SRT8, Dodge Magnum SRT8, and Jeep Grand Cherokee SRT8 models. It is intended for professional engine builders and experienced enthusiasts performing engine rebuilds or performance upgrades.

Standard engine assembly procedures apply, with proper machining and clearance verification recommended to ensure optimal performance and longevity. No special modifications beyond typical rebuild practices are required.
