Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear. Ferrea Racing Components valve springs are developed from high strength alloys, including premium grade chrome silicon steel.\u003c\/p\u003e \u003cp data-gtm-vis-has-fired-536019_202=\"1\" align=\"justify\"\u003eFerrea Racing Components springs are heat-treated and stress relieved, which dramatically increases the spring’s life. The company's valve springs provide the stability needed for high lift, and high rpm racing engines while minimizing the load loss for today’s aggressive valvetrain combinations.\u003c\/p\u003e \u003cp data-gtm-vis-has-fired-536019_202=\"1\" align=\"justify\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli data-gtm-vis-has-fired-536019_202=\"1\"\u003eControls dominant harmonics\u003c\/li\u003e \u003cli data-gtm-vis-has-fired-536019_202=\"1\"\u003eProvides needed stability\u003c\/li\u003e \u003cli data-gtm-vis-has-fired-536019_202=\"1\"\u003eReduce valvetrain component wear\u003c\/li\u003e \u003cli data-gtm-vis-has-fired-536019_202=\"1\"\u003eDeveloped from high strength alloys\u003c\/li\u003e \u003cli data-gtm-vis-has-fired-536019_202=\"1\"\u003eHeat-treated and stress relieved\u003c\/li\u003e \u003c\/ul\u003e \u003cp data-gtm-vis-has-fired-536019_202=\"1\" align=\"justify\"\u003e\u003cstrong\u003eApplication: \u003c\/strong\u003e2009+ Nissan GT-R\u003c\/p\u003e","brand":"Ferrea","offers":[{"title":"Default Title","offer_id":42891691458716,"sku":"KT4015","price":1556.79,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/6729\/1292\/products\/ferrea-racing-components-dual-spring-kit-2009-nissan-gt-r-kt4015-1158496454.png?v=1756786190","url":"https:\/\/www.mypartsguy.ca\/products\/ferrea-racing-components-dual-spring-kit-2009-nissan-gt-r","provider":"My Parts Guy MPG Auto","version":"1.0","type":"link"}
