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","brand":"KB Keith Black Performance Motorcycle Pistons","offers":[{"title":"Default Title","offer_id":59217607917942,"sku":"ZOD-724271","price":394.39,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1021\/6298\/9430\/files\/standard-rgba_3eb71e35-bb2b-4493-afe1-ff51fe6163b5.png?v=1793532648","url":"https:\/\/www.blue-bull.nl\/products\/keith-black-forged-alloy-pistons-724271","provider":"Blue Bull","version":"1.0","type":"link"}
