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.

Manley TensileMax steel valve spring retainers are designed for serious engine builders. They're as light as standard titanium retainers and within 2 to 4 grams of lightweight titanium versions. The tough alloy retainers are specially heat-treated to provide a hardness of Rc 52-54 and prevent retainer wear. Manley's exclusive process yields a part that delivers optimum balance between ultimate strength, fatigue strength, hardness, and ductility. A unique impingement process developed specifically for the TensileMax alloy and hardness range improves fatigue strength and promotes better oiling between the engine valve spring and retainer. They are available in a variety of sizes, individually or in larger sets.
