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+D6566 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.\t\t\t\t\u003cdiv class=\"product__accordion accordion\"\u003e\n\t\t\t\t\u003cdetails\u003e\n\t\t\t\t  \u003csummary aria-expanded=\"false\"\u003e\n\t\t\t\t\t\u003cdiv class=\"summary__title\"\u003e\u003ch2 class=\"h4 accordion__title\"\u003eAttributes\u003c\/h2\u003e\u003c\/div\u003e\n\u003cspan class=\"icon-caret\"\u003e\u003c\/span\u003e\t\t\t\t\t\n\t\t\t\t  \u003c\/summary\u003e\n\t\t\t\t  \u003cdiv class=\"accordion__content\"\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eCOMP Cams\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00036584283249\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eAmazon ASIN: \u003c\/b\u003eB00N6LTDAI\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eC.A.R.B.
