Racing Valve Spring Kit

KPMI? valve springs are wound from Premium Kobe Super-Clean Chrome Silicon Wire. 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.
