Better designed valve springs using state-of-the-art machinery for purpose-built racing engines. Manley Street Master valve springs are 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.
Manley Street Master valve springs feature a small diameter and are lightweight, allowing engines to rev higher faster. They have an extended tip thickness to eliminate overload breakage and their tightly controlled open-end flatness reduces valve stem side loading.
