Manley Valve Spring, SPRING-1.500 DOUBLE

From drag strips to short track and endurance circuits, the Manley NexTek® series is engineered for serious racers. NexTek® springs resist pressure loss and valve-train degradation even in the most demanding race conditions. That means more consistent spring force deep into a run, reduced valve bounce, and improved overall stability for high-RPM performance. Built to outperform and outlast in real-world competition.

  • 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 Spintron, 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 chrome silicon material
