If you have had problems with valve float or throwing rocker arms, this is the spring set that will cure your problems for good. GSC beehive springs are made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"0\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003ePart Number:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eGSC5041\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eSprings:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eBeehive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eRetainers:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eTitanium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eCoil Bind:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e1.004\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eInstall Height:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e1.539 \/ 1.519\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eSeat Pressure:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e100 \/ 107 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eOpen Pressure, 11.70mm Lift:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e250lbs @ 1.078\"\u003cbr\u003e256lbs @ 1.058\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eMaximum Valve Lift:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e0.476\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eMax RPM:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e10,500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eMax Boost:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e44 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ca style=\"color: #afafaf;\" href=\"https:\/\/stmtuned.com\/collections\/gsc-power-division-products\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more GSC Products\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"GSC","offers":[{"title":"Default Title","offer_id":50565063016790,"sku":"GSC-5041","price":448.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/GSC5041-4g63-evo-dsm-valve-springs-high-rpm.jpg?v=1749222742","url":"https:\/\/www.speed-addicts.com\/en\/products\/gsc-power-division-spring-retainer-sets-4g63","provider":"Speed Addicts","version":"1.0","type":"link"}
