Expected to become the new standard in high performance valve spring design, COMP Cams Conical and Dual Conical Valve Springs utilize round wire and feature a diameter-driven and progressive- pitch-driven natural frequency. This design increases the valve train RPM limit while reducing resonance concerns and decreasing dynamic spring oscillations. The result is longer spring life and the ability to run more aggressive camshafts. A breakthrough in valve spring development, COMP Cams is the very first to market with this advanced conical design.

• Superfinish surface processing increases both lift capability and spring longevity without increasing wire size
• The best natural frequency damping setup dampens without wear, heat/friction or risk from interference contact
• Designed for circle track, road race and drag racing applications, as well as all-out, high-RPM street/strip hydraulic roller valve train systems with optimized lifters
