Chrysler 6.1L HEMI 4.060in Bore 1.085in Compression Dome -11.5cc Stroker

598660CE-8

Overview:

The Manley Performance Platinum Series Extreme Pistons are precision-engineered components designed specifically for the Chrysler 6.1L HEMI engine with a 4.060-inch bore and 1.085-inch compression dome. This set of eight forged pistons is ideal for enthusiasts and professional engine builders seeking to enhance the durability and performance of stroked HEMI builds.

Crafted from high-strength 2618 alloy, these pistons provide excellent resistance to heat and stress, making them well-suited for high-performance street, strip, and racing applications. Whether you are upgrading your engine for increased displacement or building a stroker motor, these pistons deliver reliable strength and precision fitment.

With their dished -11.5cc design, these pistons help optimize compression ratios for improved combustion efficiency and power output. You’ll benefit from enhanced engine longevity and consistent performance under demanding conditions.

Key Features:

Manley’s Platinum Series Extreme Pistons incorporate advanced materials and design features to meet the needs of serious engine builders:

• Forged from premium 2618 aluminum alloy for superior strength and thermal resistance
• Proven cam and barrel skirt profiles reduce friction and wear for improved durability
• Tool steel wrist pins provide enhanced strength and reliability under high loads
• Moly skirt coatings on select part numbers reduce friction and improve piston ring sealing
• Dished piston design with -11.5cc volume to optimize compression ratio for stroker applications
• Precision machining ensures exact bore and dome dimensions for consistent engine performance
• Set of eight pistons engineered for balanced performance in V8 HEMI engines
• Trusted by professional engine builders and tuners worldwide for high-performance builds

Construction & Design:

These pistons are crafted using a forged 2618 aluminum alloy, known for its excellent strength-to-weight ratio and ability to withstand high combustion pressures and temperatures. The cam and barrel skirt profiles have been extensively tested to reduce piston slap and improve skirt stability during operation.

The tool steel wrist pins are precision-hardened to resist bending and wear, ensuring a secure connection between the piston and connecting rod. Additionally, the moly skirt coating applied on select models reduces friction between the piston skirt and cylinder wall, enhancing ring seal and reducing wear over time.

The dished piston crown with a -11.5cc volume is designed to complement stroker crankshafts, helping to maintain optimal compression ratios and combustion chamber dynamics for improved power and efficiency.

Installation & Fitment:

This piston set is designed as a direct fit for Chrysler 6.1L HEMI engines with a 4.060-inch bore and 1.085-inch compression dome. Installation requires standard engine assembly procedures and precision machining to ensure proper ring end gaps and clearances.

These pistons are intended for stroked engine builds and should be installed by experienced engine builders or professionals familiar with performance engine assembly. No special modifications to the block or rods are required beyond typical stroker kit components.

What's Included:

• Set of 8 forged 2618 aluminum alloy pistons
