By coupling these developments with strict KPMI® design protocols and employing multiple design, simulation, and FEA analysis software, we were we able to overcome the torsional stresses unique to ovate wire springs that previously severely limited their operating parameters. KPMI® Beehive Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened. The hardened steel basewashers included in these kits are designed to locate the spring and control lateral movement. KPMI® made OEM replacement seals are included for a more complete performance valvetrain solution.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 608px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 26px;\"\u003e\n\u003ctd style=\"width: 205.068px; text-align: right;\"\u003eInstallation Instructions\u003c\/td\u003e\n\u003ctd style=\"width: 388.043px;\"\u003e\u003ca href=\"http:\/\/media.kpmi.us\/ins\/999-102850.pdf\" target=\"_blank\"\u003eClick Here\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23px;\"\u003e\n\u003ctd style=\"width: 205.068px; text-align: right;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"width: 388.043px;\"\u003eIntake\/ Exhaust\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 30px;\"\u003e\n\u003ctd style=\"width: 205.068px; text-align: right;\"\u003eRetainer Material\u003c\/td\u003e\n\u003ctd style=\"width: 388.043px;\"\u003eH.T.
