KPMI® valve springs are heat-treated, stress relieved, and shot peened to insure maximum performance and life. Springs are engineered for each specific application using proprietary advanced spring design simulation, and analysis software. Engineers pay special attention to cam and spring harmonics, stress, mass, and operating rpm.\n\u003cp\u003eThe KPMI Racing Valve Spring Kit is engineered for high-performance boosted racing applications. KPMI valve springs are wound from Premium Kobe Super-Clean Chrome Silicon Wire and are heat-treated, stress relieved, and shot peened to support performance and service life.\u003c\/p\u003e\u003cp\u003eKPMI engineers each spring for its specific application using proprietary spring design simulation and analysis software. The design process considers cam and spring harmonics, stress, mass, and operating RPM to help deliver the required spring performance.\u003c\/p\u003e\u003cp\u003eThis kit provides 80 pounds of seat pressure and 205 pounds at 0.435 inches of lift maximum. It includes lightweight heat-treated steel retainers and beehive springs designed to reduce reciprocating mass while providing the spring forces required for demanding racing use. The spring kit is designed for compatibility with the OEM integrated seal\/base, OE number 3610212, where applicable.\u003c\/p\u003e\u003cp\u003eKPMI combines application-specific engineering with treated spring and retainer components in this Racing Valve Spring Kit, part number 80-80030.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSeat Pressure: 80 pounds of seat pressure and 205 pounds at 0.435 inches of lift maximum\u003c\/li\u003e\n\u003cli\u003eSpring Material: Wound from Premium Kobe Super-Clean Chrome Silicon Wire\u003c\/li\u003e\n\u003cli\u003eSpring Treatment: Heat-treated, stress relieved, and shot peened\u003c\/li\u003e\n\u003cli\u003eApplication Engineering: Designed for the specific application using proprietary spring design simulation and analysis software\u003c\/li\u003e\n\u003cli\u003eOEM Compatibility: Designed for compatibility with the OEM integrated seal\/base, OE number 3610212, where applicable\u003c\/li\u003e\n\u003cli\u003eRetainers and Springs: Lightweight heat-treated steel retainers and beehive springs reduce reciprocating mass\u003c\/li\u003e\n\u003cli\u003eRacing Application: Provides spring forces required by high-performance boosted racing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"KPMI","offers":[{"title":"Default Title","offer_id":68134554501305,"sku":"191-24006","price":242.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.thespeedshopusa.com\/fr\/products\/kpmi-racing-valve-spring-kit-80-80030","provider":"THE SPEED SHOP USA","version":"1.0","type":"link"}
