These are custom forged pistons for the LTG engine, made for us by Diamond to our specs. They use the high performance 2618 forging and are 9.5:1 compression. These also have horizontal gas ports to help the top ring seal better. To finish these off we upgraded the wrist pins to a thicker wall H13 tool steel. In our experience most ecotec pistons come with a weak pin that can flex under high cylinder pressure. This causes premature piston wear and unstable ring sealing of the cylinders.
