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 manufactures these valve springs from Premium Kobe Super-Clean Chrome Silicon Wire, then heat-treats, stress-relieves, and shot-peens them to support performance and service life.\u003c\/p\u003e\u003cp\u003eKPMI engineers each spring for its specific application using advanced 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\u003eThe kit provides 80 pounds of seat pressure and 205 pounds at 0.435-inch maximum lift. Its lightweight, heat-treated steel retainer and beehive spring design help reduce reciprocating mass while providing the spring forces required for high-performance boosted racing applications. The KPMI spring kit is designed for compatibility with the OEM integrated seal\/base, OE number 3610212, where applicable.\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-inch maximum lift\u003c\/li\u003e\n\u003cli\u003eMaterial: Wound from Premium Kobe Super-Clean Chrome Silicon Wire\u003c\/li\u003e\n\u003cli\u003eSpring Treatment: Heat-treated, stress-relieved, and shot-peened for performance and service life\u003c\/li\u003e\n\u003cli\u003eApplication Design: Engineered for each specific application using advanced spring design simulation and analysis software\u003c\/li\u003e\n\u003cli\u003eRetainer and Spring: Lightweight heat-treated steel retainer and beehive spring reduce reciprocating mass\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\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":68134553583801,"sku":"191-24007","price":228.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.thespeedshopusa.com\/products\/kpmi-racing-valve-spring-kit-80-80410","provider":"THE SPEED SHOP USA","version":"1.0","type":"link"}
