Product Details

The COMP Cams 977-12 valve springs are precision-engineered performance springs designed specifically for use with COMP Cams 972 series hydraulic roller lifters. These springs feature a 1.460-inch outer diameter and deliver the proper seat pressure and open pressure characteristics needed for reliable valve train operation with hydraulic roller camshafts.

Key Features:

  • 1.460-inch outer diameter designed for 972 series lifter compatibility
  • Engineered spring rates for hydraulic roller camshaft applications
  • Precision wound from high-quality chrome silicon steel
  • Consistent coil spacing ensures proper valve control throughout the RPM range
  • Reduces valve float and maintains positive valve control

COMP Cams valve springs are manufactured to strict tolerances to ensure consistent performance and durability. These springs provide the optimal balance of seat pressure and spring rate needed for street performance and mild racing applications using hydraulic roller lifters.
