Description

Part #: 221455-16

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.

Valve Spring - NexTek - Dual Spring - 797 lb/in Spring Rate - 1.130 in Coil Bind - 1.500 in OD - Set of 16
