{"product_id":"29mm-x-99mm-6mm-stem-back-cut-valves-set-of-12","title":"29mm x 99mm 6mm Stem Back Cut Valves (Set of 12)","description":"The GSC Power-Division 23-8N Exhaust Valve Set is engineered to be a high-performance, durable valvetrain component for demanding engine applications. Utilizing advanced 3D design and simulation, GSC has developed a stronger, higher-flowing valve head that minimizes distortion under extreme conditions, leading to better sealing and consistent performance over the life of the valve.\n\nConstructed from robust 23-8N Nitride material with a polished chrome finish, these valves feature a 29mm head diameter and a 99mm length, with a 6mm stem diameter. The inclusion of a back cut on the valve head serves to reduce weight, enabling higher RPM operation, increased boost pressure, and the ability to accommodate more aggressive cam profiles without requiring higher valve spring seat pressures. The swirl-polished heads also contribute to smoother airflow over the valve.\n\nThese valves are designed to be a direct replacement for Toyota 2JZ-GE and 2JZ-GTE engines, fitting models from 1993 to 2005, including Lexus GS300 and IS300. The set contains 12 exhaust valves.","brand":"GSC Power-Division","offers":[{"title":"Default Title","offer_id":52688623927608,"sku":"GSC2061-12","price":225.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663179401.webp?v=1784891995","url":"https:\/\/store.motormia.co\/products\/29mm-x-99mm-6mm-stem-back-cut-valves-set-of-12","provider":"MOTORMIA","version":"1.0","type":"link"}
