The Manley NexTek drag race valve spring set is a competition-grade kit for high-RPM race engines, offered as a set of 16 springs sized for 1.500in OD applications. NexTek springs resist pressure loss and valvetrain degradation under demanding conditions, delivering more consistent spring force, reduced valve bounce and improved stability. Dual spring design and lightweight materials raise natural frequency and lower active mass for higher RPM potential.
