{"product_id":"inconel-performance-exhaust-valves-30v","title":"Inconel Performance Exhaust Valves, 30V","description":"The Supertech ST-30V is a performance exhaust valve set containing 12 Inconel valves, specifically designed as a robust starting point for 30V cylinder head builds. These Inconel valves provide significantly greater reliability and heat resistance than traditional OEM stainless steel or sodium-filled exhaust valves, which are prone to crumbling under stress.\n\nFor builders aiming for the absolute highest levels of performance, Supertech also offers these valves in a +1mm oversize option, which requires machine work but maximizes flow potential. Additionally, single groove keeper setups are available for applications requiring extremely high RPM stability, as these grip the valve shaft directly for enhanced security.","brand":"Supertech","offers":[{"title":"Default Title","offer_id":52866419687736,"sku":"st-30v","price":280.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687705122.webp?v=1787907542","url":"https:\/\/store.motormia.co\/products\/inconel-performance-exhaust-valves-30v","provider":"MOTORMIA","version":"1.0","type":"link"}
