Overview:

The Manley Chrysler 6.1L HEMI Extreme Duty Piston Set is engineered for enthusiasts and professional engine builders seeking reliable, high-performance components for their 6.1L HEMI engines. Designed to withstand the rigors of high horsepower and demanding conditions, these pistons offer a perfect balance of strength, durability, and precision fitment.

Whether you are building a street performance engine, a track-ready powerplant, or a high-output daily driver, this piston set provides the quality and technology needed to enhance your engine’s longevity and performance. You’ll get pistons crafted from premium materials with advanced design features that support increased power and durability.

Key Features:

Manley’s Platinum Series pistons incorporate advanced materials and design elements to deliver superior performance and reliability:

• Forged from 2618 aluminum alloy, known for excellent strength and fatigue resistance under extreme conditions.
• Proven cam and barrel skirt profiles reduce friction and wear for improved efficiency and longevity.
• Tool steel wrist pins provide enhanced strength and durability at critical pivot points.
• Moly skirt coatings on select part numbers reduce friction and help protect against scuffing.
• 11.5cc dished piston design optimizes combustion chamber volume for precise compression control.
• 4.065-inch bore and 3.579-inch stroke dimensions engineered specifically for Chrysler 6.1L HEMI applications.
• Extreme duty construction suitable for high-performance, forced induction, and naturally aspirated builds.

Construction & Design:

These pistons are crafted using high-quality 2618 alloy forgings, a material favored in motorsports and high-performance applications for its ability to endure elevated temperatures and stresses. The cam and barrel skirt profiles have been refined to minimize friction and wear, contributing to smoother operation and longer engine life.

The inclusion of tool steel wrist pins enhances the pistons’ ability to handle high loads without deformation, while the moly skirt coatings on select models further reduce friction between the piston skirts and cylinder walls. The -11.5cc dish design helps optimize combustion chamber shape and compression ratio, supporting efficient power delivery and engine tuning flexibility.

Installation & Fitment:

This piston set is designed as a direct replacement for Chrysler 6.1L HEMI engines with a 4.065-inch bore and 3.579-inch stroke. It fits applications requiring a -11.5cc dished piston configuration. Installation requires standard engine assembly procedures and precision machining to ensure proper clearances and fitment.

These pistons are intended for professional engine builders and experienced enthusiasts familiar with high-performance engine assembly. No cutting or modification of the pistons is necessary when used within the specified engine parameters.

What's Included:

• Complete set of forged 2618 alloy pistons with -11.5cc dish volume
