Description
Part #: 221449P-16
From drag strips to short track and endurance circuits, the Manley NexTek (R) series is engineered for serious racers. NexTek (R) 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.
