Kibblewhite Valve Spring Kits Kibblewhite springs are engineered for each specific application using proprietary advanced spring design, simulation, and anaylsis software. Engineers pay special attention to cam and spring harmonics, stress, mass, and operating RPM. Springs are constructed from Premium grade, super clean ground chrome silicon wire. X-Rayed at regular intervals to check for inclusions, heat treated, and shot peened. Insuring maximum spring life.
