Spring Retainer Set

Manley TensileMax Steel Retainers combine exceptional strength, fatigue resistance, and wear durability in a lightweight design that approaches titanium retainer weights. Manufactured from a proprietary TensileMax alloy, precision CNC machined, heat treated, and finished with Manley exclusive impingement process, they deliver reliable high-RPM valvetrain performance for demanding racing and performance engine applications.

Part Type

Engine Valve Spring Retainer Set

• Designed to be as light as standard titanium retainers and very close in weight to lightweight titanium versions (within 2-4 grams)
• Manufactured from our incredibly tough TensileMax alloy
• Optimum balance between ultimate strength, fatigue strength, hardness, and ductility
• Specially heat treated to provide a hardness of Rc 52-54 and prevent retainer wear
• Unique impingement process that improves fatigue strength and promotes better oiling between the spring and retainer
