Description

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 ensure 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.

  • Includes forged one-piece stainless steel intake valves, wound chrome-silicon heat-treated wire valve springs, ultra-light titanium retainers and hardened steel bases
  • Components are created using Finite Element Analysis (F.E.A.) software, as well as proprietary camshaft analysis and spring design software
