Product Details

COMP Cams Race Endurance Dual Valve Springs are performance engine valve springs (valve spring kits) built for serious oval track and drag racing engines. They are designed to keep the valvetrain stable and controlled in high-RPM, high-lift race applications, particularly with solid roller cams and nitrided solid lifters.

Key Features:

  • Dual spring design: Two springs per valve give more strength than a single spring. They handle the extra lift and stress found in demanding race engines.
  • Super Clean wire: The springs are made from premium wire and go through extensive quality control testing for strength, durability and valvetrain stability.
  • Race Endurance finishing: Enhancements added during the finishing process improve stability and service life.
  • Built for racing: The series suits applications with better valves, retainers and keepers. In those setups, the springs typically run closer to coil bind.
  • Choice of specifications: The line is offered in several outside diameters, installed heights, spring rates and lift capabilities. This lets engine builders match the spring to their cylinder heads and cam.

COMP Cams is a well-known name in racing valvetrain components. Its Race Endurance dual valve springs give engine builders a durable, consistent way to improve valve control and engine reliability. Check the specifications on each part number to confirm it matches your heads, cam and valvetrain components.
