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
- No degradation of spring pressure in the later stages of a race
- Specially processed premium-grade chrome silicon that is virtually free of impurities or surface irregularities
- Tested by leading engine builders and are confirmed to be the best performing valve springs on the market today
