{"product_id":"rb20det-vg30dett-nitrided-valve-spring-kit","title":"RB20DET\/VG30DETT Nitrided Valve Spring Kit","description":"The Tomei valve spring kit is engineered for RB20DET\/VG30DETT engines, offering approximately 10.35mm of lift. Constructed from nitrided chromoly silicone (SWOCN-V material variant), these springs are built for high performance and high RPM applications, exhibiting significant resistance to fatigue. The nitriding process enhances surface compression repulsion, increasing the fatigue limit by 1.5 times when combined with the oil-tempered chromium-silicone alloy steel wire. This makes them suitable for engines revving up to 10,000 RPM, even with high-lift camshafts. These springs are specifically required for use with Tomei Procams to achieve optimal performance. The kit is compatible with stock intake and exhaust valves.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873034858808,"sku":"TA304A-NS07A","price":270.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/rb20det-vg30dett-nitrided-valve-spring-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
