Professional engine builders and elite tuners around the world are running Manley pistons for some very good reasons.
Constructed from durable, high quality 2618 alloy forgings. Features "Cam and Barrel" profiles that make big power, yet are friendly to the cylinder walls. Total seal piston rings are used exclusively. Unique (to Manley) fixturing allows skirt turning & ring groove machining to be performed in one single operation. This ensures the ultimate ring groove to skirt squareness.
