Description

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. They have an extended tip thickness designed to eliminate overload breakage, and their tightly controlled open end flatness reduces valve stem side loading.
