Manley Performance NexTek Series 1.640 OD / .8602 ID / .900 Lift Sportsman and Bracket Classes Valve Springs – Set of 16 (221425-16) Manley Performance

NexTek® Series Sportsman and Bracket Classes Drag Race Valve Springs – Set of 16 by Manley Performance

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.
