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.
Designed to be as light as standard titanium retainers and very close in weight to lightweight titanium versions (within 2-4 grams)
Unique impingement process that improves fatigue strength and promotes better oiling between the spring and retainer
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
Manufactured from our incredibly tough TensileMax alloy
