To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to the material structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip. – Valve Tip Length 3.7mm – Stem Diameter 5.96mm.\u003c\/p\u003e\u003cp\u003e– Valve Length 106mm – Valve Head Size 0.040″ \/ 1mm – Valve Head Diameter 31.5mm – Valve Type Exhaust – Valve Stem Diameter 5.96mm – Valve Material Stainless Steel, Super Alloy – Valve Face Dish Replaces OEM Part # 11-34-1-739-823 \/ 11 34 1 739 823 \/ 11341739823.\u003c\/p\u003e","brand":"mavexi","offers":[{"title":"Default Title","offer_id":53219255517365,"sku":"YFLAR253417","price":65.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1030\/0820\/7029\/files\/ExhaustValves12_41c02521-83db-4b51-84ce-811d40ce5be7.webp?v=1788626479","url":"https:\/\/mavexi.shop\/products\/ferrea-competition-plus-exhaust-valve-kit-31-5mm-1mm-bmw-m50-m51-m52-m54-s50","provider":"mavexi","version":"1.0","type":"link"}
