This design increases the valve train RPM limit while reducing resonance concerns and decreasing dynamic spring oscillations. The result is longer spring life and the ability to run more aggressive camshafts. A breakthrough in valve spring development, COMP Cams® is the very first to introduce this advanced conical design.\u003c\/p\u003e\u003cp\u003eConical Valve Springs:\u003c\/p\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\u003cdiv style=\"margin-left: 2em\"\u003e\n\u003cul\u003e\n\u003cli\u003eReduced mass improves RPM stability\u003c\/li\u003e\n\u003cli\u003eConical design offers the best natural frequency damping\u003c\/li\u003e\n\u003cli\u003eDampens w\/o wear, heat\/friction or risk from interference contact\u003c\/li\u003e\n\u003cli\u003eProgressive frequency increases RPM limit \u0026amp; allows for more aggressive cams\u003c\/li\u003e\n\u003cli\u003eSuperfinish surface processing increases both max lift capability \u0026amp; valve spring longevity\u003c\/li\u003e\n\u003cli\u003eConstantly decreasing diameter from bottom to top reduces active mass \u0026amp; decreases applied forces; Result is longer valve train component life \u0026amp; less parasitic horsepower loss.\u003c\/li\u003e\n\u003cli\u003eReduced oscillation in Conical Springs translates to less applied force and stress to the springs. This increases the lifespan of the spring and the valve train. It also allows the use of more aggressive camshaft profiles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOuter Diam.: \u003c\/strong\u003e1.060\" (Top)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOuter Diam.:\u003c\/strong\u003e1.332\" (Bottom)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInner Dia.:\u003c\/strong\u003e.660\" (Top)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInner Dia.:\u003c\/strong\u003e.932\" (Bottom)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSeat Load:\u003c\/strong\u003e 145 @1.900\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOpen Load:\u003c\/strong\u003e 495 @1.225\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCoil Bind:\u003c\/strong\u003e 1.185\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRate: \u003c\/strong\u003e520\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e","brand":"FR SPORT","offers":[{"title":"Default Title","offer_id":42823040499774,"sku":"0HV5P","price":404.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/1123\/3598\/files\/7885394b74f381f30e1bb7ff3244f658_9619f573-4bfd-427f-be18-65233ee03b25.jpg?v=1779612455","url":"https:\/\/turbotechperformance.com\/products\/comp-cams-conical-valvespring-660-932","provider":"TURBO TECH PERFORMANCE","version":"1.0","type":"link"}
