Dualoy Diesel pistons are cast and machined in-house to maintain the highest level of quality and consistency. All Dualoy pistons feature a high strength top ring carrier to improve strength of the top land, and resistance to the extreme heat of diesel engines. Oil cooling galleries are cast into the pistons, as required depending on the specific application.
