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
