In this video, Billy Godbold, chief cam designer and astrophysicist at COMP Cams, explains how COMP Cams’ conical valve springs help control heat and friction by dampening spring vibrations and provide much longer spring life than cylindrical or even beehive designs.

The conical springs are perfect for the racer wanting to run a more-aggressive camshaft, COMP Cams says.

By progressively reducing the diameter of the spring from the bottom coil to the top, COMP Cams says conical springs offer several advantages, including:

  • Natural dampening without an additional spring creating more heat and friction.
  • About a 33-percent reduction in spring weight and mass relative to a typical dual spring.
  • The top of the spring generates less load over the nose at peak lift when the spring is fully compressed, and that reduced load is a major factor in the increased life of the springs and valvetrain.
