    High-Performance Valve Springs with Unique Cone Shape

    Comp Cams Conical Valve Springs are designed with a progressive pitch-driven natural frequency that increases valve train RPM limits while reducing resonance concerns and decreasing dynamic spring oscillations. This results in longer spring life and the ability to run a more aggressive camshaft.

    Features
  • Conical design dampens without wear, heat/friction, or risk of contact interference
  • Progressive frequency increases RPM limit to accommodate more aggressive camshafts
  • Variable spring diameter minimizes active mass & applied force for less power loss, better RPM stability, and longer component life
