Manley NexTek valve spring set of 16 designed for high‑RPM and racing use, with a .950in lift and 1.522in OD. NexTek springs resist pressure loss and valvetrain degradation under extreme conditions to reduce valve bounce and maintain consistent spring force deep into a run. The dual‑spring, lightweight design lowers active mass, improves valvetrain control and supports higher rev limits in competitive engines.
