Manley extreme-duty piston set for Ford 4.6L/5.4L SOHC/DOHC engines with 3.552in bore and -18cc spherical dish. These Platinum Series-style pistons use 2618 alloy forgings, chrome-moly wrist pins, and moly skirt coatings on select SKUs to balance strength and ring seal. Manley's machining fixturing and tight ring land tolerances help deliver durability and reliable sealing for high-output builds.
