Description
Valve spring performance directly impacts engine reliability at high RPM, and Manley’s NexTek dual springs deliver the consistent load rates necessary for aggressive cam profiles without coil bind failure. Built with premium materials and precision engineering, these springs maintain their rate consistency across extended heat cycles—critical for forced induction and naturally aspirated builds pushing beyond stock parameters. If you’re running a serious street or track engine, upgrading to quality dual springs prevents valve float and ensures predictable power delivery.
