Valve Spring - NexTek - Dual Spring / Damper - 534 lb/in Spring Rate - 1.190 in Coil Bind - 1.570 in OD - Polished - Set of 16

Valve Spring

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.

These Manley NexTek valve springs are better-designed valve springs using state-of-the-art machinery for purpose-built racing engines. They're manufactured from super-clean, high-tensile chrome silicon steel and are shot-peened to MIL specs for maximum fatigue life. They feature a proprietary, multi-step heat-treating that minimizes load loss and have computer-aided modeling to minimize valve bounce and valve gear separation. The Manley NexTek valve springs are smaller diameter and lightweight, allowing engines to rev higher faster. They have an extended tip thickness designed to eliminate overload breakage, and their tightly controlled open-end flatness reduces valve stem side loading.
