The Manley Performance Platinum Series Piston Set is precision-engineered for the Chrysler 6.1L HEMI engine with a 4.080-inch bore and 3.579-inch stroke. Designed for professional engine builders and serious enthusiasts, this piston set delivers exceptional strength, durability, and reliability for high-performance applications. Whether you are assembling a street performance engine or a race-ready build, these pistons provide the durability and precision required to withstand increased cylinder pressures and aggressive tuning.
With a proven design that enhances combustion efficiency and long-term engine durability, the Manley Platinum pistons are an ideal upgrade for those seeking to improve power output and engine longevity in their 6.1L HEMI-powered vehicles.
Manley’s Platinum Series pistons incorporate advanced materials and design innovations to ensure superior performance and reliability in demanding conditions:
These pistons are crafted from 2618 alloy, a high-strength forged aluminum known for its excellent thermal fatigue resistance and toughness in extreme engine environments. The forging process produces a dense, uniform grain structure that withstands the intense combustion pressures and temperatures typical of high-output HEMI engines.
Manley’s meticulous engineering is evident in the cam and barrel skirt profiles, which minimize piston slap and friction while maintaining durability. The inclusion of tool steel wrist pins adds strength where it is most critical, and the molybdenum skirt coatings on select pistons further reduce wear and friction against cylinder walls.
The -11.5cc dished piston crown is specifically designed to complement the 6.1L HEMI’s combustion chamber geometry, enabling precise control of compression ratio and promoting efficient combustion for improved performance and reliability.
This piston set is a direct replacement for Chrysler 6.1L HEMI engines with a 4.080-inch bore and 3.579-inch stroke. It is compatible with both stock and aftermarket components designed for this engine displacement and bore size. Typically, no modifications to the engine block are necessary, making these pistons suitable for rebuilds and performance upgrades alike.
Professional installation is recommended to ensure proper piston ring end gap, piston-to-wall clearance, and wrist pin fitment, guaranteeing optimal performance and longevity.
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!
