Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitrided which is most popular in European and Japanese motors.\u003c\/inline\u003e\u003cbr\u003e\u003cinline style=\"font-size: 14px;\"\u003e\u003c\/inline\u003e\u003cbr\u003e\u003cinline style=\"font-size: 14px;\"\u003e\u003c\/inline\u003e\u003cb style='font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif;'\u003eSpecs:\u003c\/b\u003e\n\u003c\/p\u003e\n\u003cul style='font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif;'\u003e\n\t\u003cli\u003e\n\u003cb style='font-weight: bold; font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px;'\u003e\u003c\/b\u003e\u003cspan style='font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px;'\u003eHead Diameter - 30.50mm (STD)\u003c\/span\u003e\n\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan style='font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px;'\u003eLength - 105.65mm\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan style='font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px;'\u003eMaterial - Inconel\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan style='font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px;'\u003eStem Diameter - 5.96mm\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cb\u003eNote: \u003c\/b\u003eTo be used with KPR-6S\/7. \u003cb\u003ePRICED INDIVIDUALLY.\u003c\/b\u003e\u003cbr\u003e\n\u003cp\u003e\n\u003c\/p\u003e\n\u003cp style='box-sizing: border-box; margin-bottom: 1em; line-height: 1.6; color: rgb(0, 0, 0); font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px; letter-spacing: normal; background-color: rgb(255, 255, 255);'\u003e\n\t\u003cstrong style=\"box-sizing: border-box;\"\u003e\u003cbr\u003eSupertech High Performance Race Engine Valves features:\u003c\/strong\u003e\n\u003c\/p\u003e\n\u003cul style='box-sizing: border-box; margin-bottom: 1em; padding: 0px 0px 0px 1.5em; list-style-position: outside; list-style-image: initial; line-height: 1.6; color: rgb(0, 0, 0); font-family: \"Helvetica Neue\", Helvetica, Arial, sans-serif; font-size: 15px; letter-spacing: normal; background-color: rgb(255, 255, 255);'\u003e\n\t\u003cli style=\"box-sizing: border-box;\"\u003e\u003cspan style=\"box-sizing: border-box; font-size: 12px;\"\u003eThe microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli style=\"box-sizing: border-box;\"\u003e\u003cspan style=\"box-sizing: border-box; font-size: 12px;\"\u003eSurface finish is smoother than with chromed stems, having less friction between stem and guide.\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli style=\"box-sizing: border-box;\"\u003e\u003cspan style=\"box-sizing: border-box; font-size: 12px;\"\u003eValve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other \"explosive\" mixes.
