Product Details

COMP Cams Dual Valve Springs are performance engine valve springs. Each valve gets two nested springs, an outer and an inner, which gives more spring pressure and better valve control than a single spring. They suit performance street, street/strip, and race engines with aggressive camshafts and higher RPM.

Key Features:

  • Dual-spring design with nested outer and inner springs for strong valve control
  • Matched spring pressure with the valve on the seat and at maximum lift, to support valvetrain stability
  • Made from quality spring wire and tested for strength and durability
  • Some versions add a damper for extra stability, and some use special surface finishing. Check each part number for its design.
  • Made in the USA by COMP Cams, a long-standing name in camshafts and valvetrain components

Valve springs have to be matched to your camshaft for the engine to reach its full potential. A cam that can turn high RPM only performs if the springs can control the valve. Choose the spring for your cam's lift and recommended spring pressure. Each part number in this line lists its own specifications.
