Manley Performance Platinum Series pistons for Chrysler 6.1L Hemi stroker assemblies are forged from 2618 alloy and feature proven cam and barrel skirt profiles plus chrome-moly wrist pins. Their manufacturing emphasizes precise ring land and groove tolerances, moly skirt coatings on select SKUs, and fixturing that ensures groove-to-skirt squareness—attributes chosen by professional engine builders for durability and consistent ring seal in high-output engines.
