Pistons are formed in a forging press an then fully machined. the combination of this alloy and forging process allows the piston to flex under detonation or pre-ignition, giving the best resistance to cracking. Since 4032 alloy has a low expansion rate but higher than the Keith Black Hypereutectic pistons, it will require a .001\" wider piston to wall clearance. Keith Black forged alloy pistons are suited for High Performance street and race applications including high compression and NOS equipped bikes. All pistons come with a set of Hastings piston rings, piston pins and spiral piston lock rings.\u003c\/p\u003e\n\u003cp\u003eKB Forged Pistons BT84-99 10.5:1 3.538\"\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Pistons \u0026amp; Piston Rings\u003c\/li\u003e\u003c\/ul\u003e","brand":"KB Keith Black Performance Motorcycle Pistons","offers":[{"title":"Default Title","offer_id":62567289979210,"sku":"724300","price":4343.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/standard-rgba_41ccfe6b-7e99-42bc-968e-2732382742bc.png?v=1782770365","url":"https:\/\/partsdenmark.se\/products\/kb-keith-black-performance-motorcycle-pistons-keith-black-forged-alloy-pistons-engine-74","provider":"Parts Denmark","version":"1.0","type":"link"}
