Product Details

The COMP Cams 981-12 is a high-performance dual valve spring designed for racing and high-lift camshaft applications. This spring features a 1.254" outer diameter and is engineered to provide reliable valve control at high RPM while preventing valve float and maintaining consistent valve timing.

Key Features:

  • 1.254" outer spring diameter for compatibility with standard valve spring pockets
  • Dual spring design with inner and outer springs for superior valve control
  • Manufactured from high-quality chrome silicon steel for durability and longevity
  • Precision wound to exacting tolerances for consistent performance
  • Ideal for performance street and racing applications with aggressive camshaft profiles

COMP Cams valve springs are heat-treated and stress-relieved to resist coil bind and maintain proper spring tension throughout the RPM range. These springs are designed to work with performance rocker arm systems and high-lift camshafts, making them an essential upgrade for serious engine builders.
