The self damping characteristic of conical geometry, along with the lower spring kinetic energy of the upper coils, provide a game-changing breakthrough in valve spring design. COMP Cams® Dual Conical Valve Springs are constrained at the top and bottom with stepped retainers and spring seats to create separation. The result is that the springs' naturally progressive nature can provide outstanding damping without rubbing friction or the associated heat and surface damage. These springs are designed for circle track, road race and drag racing applications, as well as all-out, high-RPM street\/strip hydraulic roller valve train systems with optimized lifters.\u003cul\u003e\n\u003cli\u003eDampen coil oscillations, increase RPM limit \u0026amp; reduce resonance\u003c\/li\u003e\n\u003cli\u003eImproves valve train stability\u003c\/li\u003e\n\u003cli\u003eFewer parasitic horsepower losses \u0026amp; more power\u003c\/li\u003e\n\u003cli\u003eSuperfinish surface processing\u003c\/li\u003e\n\u003cli\u003eNon-interference fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\n\u003cbr\u003eSpecs:\u003c\/div\u003e\u003cdiv\u003eNumber of Springs Per Valve: Dual\u003cbr\u003eOutside Diameter: 1.442\"\/1.657\"\u003cbr\u003eCoil Bind Heigh 1.115\"\u003cbr\u003eSpring Rate (lbs\/in): 600 lbs.\/in.\u003cbr\u003eInside Diameter of Outer Spring: .646\"\/.861\"\u003cbr\u003eSeat Load: 150lbs @ 2.00\" \u003cbr\u003eOpen Load: 630lbs @ 1.20\" \u003cbr\u003eValve Spring Style: Conical\u003cbr\u003eCoated: No\u003cbr\u003eQuantity: Sold as a set of 16.\u003cbr\u003e\n\u003c\/div\u003e\u003cdiv\u003e\n\u003ca target=\"_blank\" href=\"http:\/\/cgi.ebay.com.au\/ws\/eBayISAPI.dll?ViewItem\u0026amp;item=161937856011\u0026amp;refid=store\u0026amp;ssPageName=STORE:HTMLBUILDER:SIMPLEITEM\"\u003eClick here for Tool Steel Retainers to Suit\u003c\/a\u003e\u003cbr\u003e\u003ca target=\"_blank\" href=\"http:\/\/cgi.ebay.com.au\/ws\/eBayISAPI.dll?ViewItem\u0026amp;item=181982548443\u0026amp;refid=store\u0026amp;ssPageName=STORE:HTMLBUILDER:SIMPLEITEM\"\u003eClick here for .530\" Seats To Suit\u003c\/a\u003e\u003cbr\u003e\u003ca target=\"_blank\" href=\"http:\/\/cgi.ebay.com.au\/ws\/eBayISAPI.dll?ViewItem\u0026amp;item=161938448757\u0026amp;refid=store\u0026amp;ssPageName=STORE:HTMLBUILDER:SIMPLEITEM\"\u003eClick here for .570\" Seats to Suit\u003c\/a\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cbr\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44671546949943,"sku":"CO7245-16","price":1431.15,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/62144.jpg?v=1780429397","url":"https:\/\/enginemaster.com.au\/products\/comp-cams-dual-conical-valve-springs-co7245-16-1-442-1-657-od-646-861-id","provider":"Engine Master","version":"1.0","type":"link"}
