The Manley Performance Platinum Series Pistons are precision-forged components engineered specifically for Chrysler 5.7L HEMI engines with a 3.917-inch bore and 4.050-inch stroke. Featuring a -23cc dished design, these pistons optimize combustion chamber volume and compression ratios, making them an excellent choice for engine builders aiming to enhance performance and reliability.
Designed for professional engine builders, tuners, and serious enthusiasts, these pistons deliver exceptional strength and durability under demanding conditions. Whether building a high-performance street engine or a race-ready powerplant, Manley’s Platinum Series pistons ensure consistent power delivery and long-lasting performance.
Manley’s Platinum Series Pistons incorporate advanced engineering and premium materials to provide superior performance and durability. Key features include:
These pistons are forged from premium 2618 aluminum alloy, a material favored in racing and high-performance engines due to its excellent strength-to-weight ratio and ability to endure extreme thermal and mechanical stresses. The forging process enhances the grain structure, resulting in pistons that resist cracking and deformation under high cylinder pressures.
The cam and barrel skirt profiles have been extensively tested to minimize piston slap and friction, contributing to quieter operation and improved efficiency. Tool steel wrist pins provide a robust connection between piston and connecting rod, critical for handling the high loads generated in boosted or high-RPM engines. Additionally, the moly skirt coating reduces friction between the piston skirt and cylinder wall, minimizing wear and enhancing ring seal longevity.
This piston set is a direct fit for Chrysler 5.7L HEMI engines with a 3.917-inch bore and 4.050-inch stroke. The -23cc dish volume is designed to maintain proper compression ratios and combustion chamber geometry when paired with compatible cylinder heads and components. Installation follows standard engine assembly procedures, requiring precise measurements for ring end gaps, piston-to-wall clearance, and wrist pin fitment. No modifications to the engine block or other components are typically necessary when using these pistons within their intended application.
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!
