Product Description

Comp Cams Dual Conical Solid Roller Valve Springs

As opposed to dual cylindrical spring systems, Comp Cams "Dual Conical Valve Springs" require no interference fit to dampen spring surge. The self damping characteristic of conical geometry, along with the lower spring kinetic energy of the upper coils, provide a game-changing breakthrough in valve spring design.

Comp Cams "Dual Conical Valve Springs" are constrained at the top and bottom with stepped retainers and spring seats to create separation. The result is that the springs’ naturally progressive nature can provide outstanding damping without rubbing friction or the associated heat and surface damage. These springs are designed for circle track, road race and drag racing applications, as well as all-out, high RPM street/strip hydraulic roller valvetrain systems with optimized lifters.

  • Dampen coil oscillations, increase RPM limit & reduce resonance

  • Improves valvetrain stability

  • Fewer parasitic horsepower losses & more power

  • Super-finish surface processing

  • Non-interference fit
