Manley NexTek Series Lightweight Dual Drag Race Valve Springs
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 racetrack (including blown nitro engines) and proven highly effective
Smaller diameter, lightweight dual design allows engines to rev higher with improved valve train control
Ultra clean, high tensile strength chrome silicon material
Super Finished multi-step surface enhancement significantly improves fatigue strength
Ideal loads for multiple applications with minimal load loss.
