Due to the additional weight of roller rockers, a higher spring rate is needed to retain valvetrain stability. Whether you’re putting together a daily driver with a mild cam, a 600 hp N\/A stroker, or a turbocharged 1000 hp brawler, our Platinum Spring Kit will make sure your valves are right where your cam wants them to be at all times.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKit includes: \u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e• SP010-1 - .650” lift BTR Max Pressure Dual Valve Springs (16)\u003c\/p\u003e \u003cp\u003e• SR004-16 - BTR Titanium Retainer Set For Max Pressure Springs \u003c\/p\u003e \u003cp\u003e• SL505060-16 - BTR Spring Locator Set; .505\" ID, .060\" Thick\u003c\/p\u003e \u003cp\u003e• VS500341-16 - BTR Valve Seal Kit\u003c\/p\u003e \u003cp\u003e• CC648-16 - Valve Lock Set \u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSpring specs:\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e170 lbs @ 1.800”\u003c\/p\u003e \u003cp\u003e380 lbs @ 1.180\"\u003c\/p\u003e \u003cp\u003e450 lbs @ 1.115”\u003c\/p\u003e \u003cp\u003eCoil bind @ 1.000”\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003ch3\u003e\u003cspan style=\"background-color: #ffffff; color: #ba372a;\"\u003e\u003cstrong\u003eMEASURE YOUR VALVE GUIDES BEFORE PURCHASE!\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\u003cp\u003eFeatures:\u003c\/p\u003e\u003ctable class=\"data table additional-attributes\" id=\"product-attribute-specs-table\"\u003e \u003ccaption class=\"table-caption\"\u003eFeatures\u003c\/caption\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eBTR SKU\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"BTR SKU\"\u003eSK004\/T\/0560\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eLength\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Length\"\u003e12.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eWidth\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Width\"\u003e3.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eHeight\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Height\"\u003e4.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eWeight\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Weight\"\u003e8.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eBrand\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Brand\"\u003eBrian Tooley Racing\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePart Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Part Type\"\u003eValve Spring Kit\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eEngine Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Engine Type\"\u003eSmall Block Chevy\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eSpring Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Spring Type\"\u003eDUAL\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eMax Lift\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Max Lift\"\u003e.650\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eRetainers Included\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Retainers Included\"\u003eYES\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eValve Seals Included\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Valve Seals Included\"\u003eYES\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eLocators Included\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Locators Included\"\u003eYES\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eLocks Included\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Locks Included\"\u003eYES\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"BTR - Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":62806485926047,"sku":"SK004\/T\/0560","price":619.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0424\/7571\/6767\/files\/sk004.png?v=1780524597","url":"https:\/\/streetdrivenperformance.com\/products\/btr-max-pressure-sbc-dual-spring-kit-650-lift-with-titanium-retainers-for-roller-rockers-sk004","provider":"Street Driven Performance","version":"1.0","type":"link"}
