Designed for its specific application, taking into account cam profiles, harmonics, natural frequency of the springs, valvetrain mass, required pressure, wire stress, fatigue life, and engine rpm.

Progressively wound springs use Kobe super-clean chromium silicon (CrSi) wire that is heat treated and shot peened for durability and consistent performance.

Complete set for one engine, manufactured to rigorous standards and made in the USA. 🇺🇸
