Product Details

The COMP Cams 946-1 Race Extreme triple valve spring is engineered for high-performance racing engines that demand maximum valvetrain control at elevated RPM. This precision-manufactured spring features a 1.660-inch outer diameter and is designed for a 2.000-inch installed height, providing the aggressive seat pressure and open pressure characteristics needed for radical camshaft profiles.

Key Specifications:

  • Outer diameter: 1.660 inches
  • Installed height: 2.000 inches
  • Triple spring design for superior valve control
  • Race Extreme series construction
  • Ideal for high-lift, high-RPM racing applications

COMP Cams Race Extreme springs are manufactured from premium chrome silicon alloy and heat-treated for durability and consistent performance under extreme conditions. Sold individually.
