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.
The KPMI 30-30920 Racing Valve Spring Kit is engineered for specific high-performance applications using advanced spring design simulation and analysis. Each spring is designed with attention to cam and spring harmonics, stress, mass, and operating RPM to support reliable performance in demanding racing environments.
KPMI valve springs are wound from premium Kobe Super-Clean Chrome Silicon Wire and are heat-treated, stress-relieved, and shot-peened to promote maximum performance and service life. The kit includes a lightweight heat-treated steel retainer and beehive spring, helping reduce reciprocating mass while providing the spring forces required by high-performance boosted racing applications.
The KPMI 30-30920 kit delivers 80 lb of seat pressure and 205 lb at 0.435-inch lift maximum. It is designed for compatibility with the OEM integrated seal/base, OE number 3610212, where applicable.
