With Xylan-coated skirts for friction reduction and a fully polished crown to reflect heat, these are the most advanced pistons available for the Ford Barra. The mass of these pistons if focused heavily on the underside of the crown to create a hugely stable structure for the crown to withstand such high pressure. \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/5548\/1713\/files\/IMG_6405.jpg?v=1759830211\" alt=\"\"\u003e\u003cbr\u003e\n\u003cdiv class=\"img-caption\"\u003ePolished Crown \u0026amp; Xylan Skirts: The Ultimate Combo.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"atomic-section\"\u003e\n\u003cdiv class=\"atomic-grid\"\u003e\n\u003cdiv\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/5548\/1713\/files\/Atomic_Cosworth_F1_Series_Forged_Pistons_Ford_Barra_DOHC.jpg?v=1758865473\" alt=\"Atomic Cosworth F1 Series Forged Pistons – Ford Barra DOHC\"\u003e\u003cbr\u003e\n\u003cdiv class=\"img-caption\"\u003eSix internal struts for immense structural rigidity.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch2\u003e2.
