The Manley Extreme Duty Piston Set is engineered specifically for Chrysler 6.1L HEMI engines with a 4.060-inch bore and a 1.220-inch compression dome. Designed to meet the demands of high-performance stroker builds, these pistons offer exceptional strength, durability, and precision. Whether you are a professional engine builder or an enthusiast aiming to maximize power and reliability, this piston set delivers the robust performance required for both street and race applications.
Crafted from premium 2618 aluminum alloy forgings, these pistons feature a -1.5cc dish volume to optimize combustion chamber dynamics and compression ratios. This design enhances combustion efficiency and power output while maintaining durability under extreme conditions.
Manley’s Extreme Duty Pistons incorporate advanced materials and engineering to ensure superior performance and longevity:
These pistons are forged from premium 2618 aluminum alloy, a material favored in motorsports for its superior strength and ability to endure elevated temperatures and stresses. The cam and barrel skirt profiles have been rigorously tested to reduce piston slap and improve ring sealing, contributing to longer engine life and smoother operation.
Tool steel wrist pins provide a robust and precise connection between the piston and connecting rod, capable of handling the increased loads associated with stroker configurations. The moly skirt coating applied to select pistons further reduces friction against cylinder walls, enhancing durability and minimizing wear during high-performance use.
This piston set is designed as a direct replacement for Chrysler 6.1L HEMI engines bored to 4.060 inches with a 1.220-inch compression dome. Installation follows standard engine assembly procedures and requires no special modifications beyond typical machining and clearance checks. These pistons are ideal for stroked engine builds where precise piston-to-cylinder clearance and optimized combustion chamber volume are critical.
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!
