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:
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:
Ideal For:
Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
