Manley's Platinum Series forged pistons are built from domestic 2618 alloy forgings and use proven cam-and-barrel skirt profiles, offering a stout foundation for high-output LT1 builds. The pistons feature precise ring lands and grooves, tool-steel wrist pins, and moly skirt coatings on select SKUs to improve ring seal and cylinder compatibility. These components are aimed at professional engine builders and serious tuners.
