NexTek® Lightweight Dual Drag Race Valve Springs
Manley NexTek® Lightweight Dual Drag Race Valve Springs offer unequaled performance.

  • Manufactured from ''super clean'' HiTensile Chrome Silicon steel
  • Shotpeened to MIL Specs for maximum fatigue life
  • Proprietary multistep heat treating minimizes load loss
  • Tightly controlled open end flatness reduces valve stem side loading
  • Tip thickness designed to eliminate overload breakage
  • Higher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential
  • Dual spring design reduces friction, which generates less heat and translates into greatly reduced load loss
  • Extensively tested on the Spiritron, dyno and race track (including blown nitro engines) and proven highly effective
  • Smaller diameter, lightweight dual design allows engine to rev higher with improved valve train control
  • Accepts smaller, lighter retainers which also promotes higher revs
  • Ultra clean, high tensile strength material
  • Super Finished multi-step surface enhancement significantly improves fatigue strength
  • Ideal loads for multiple applications with minimal load loss
