Description

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.

Features & benefits

  • Manufactured from “super clean” Hi-Tensile Chrome Silicon steel
  • Tip thickness designed to eliminate overload breakage
  • Shot-peened to MIL spec for max fatigue life
  • Proprietary multi-step heat treating minimizes load loss
  • Tightly controlled open-end flatness reduces valve stem side loading
