Product Details

The COMP Cams 990-1 is a high-performance dual valve spring designed for demanding race and street applications. This spring features a 1.437-inch outer diameter with an integrated damper to control valve float and harmonics at high RPM.

Key Specifications:

  • Outer spring diameter: 1.437 inches
  • Dual spring design with inner damper spring
  • Engineered for high-lift camshafts and increased valve control
  • Provides consistent seat pressure and open pressure ratings
