What is the primary benefit of using titanium retainers?

Titanium retainers are significantly lighter than steel equivalents. This reduced mass in the valvetrain can lead to improved engine response and allow the engine to rev more freely at higher RPMs.

What does the '7-degree lock angle' mean?

The 7-degree lock angle refers to the angle of the groove where the valve lock (keeper) sits. This is a common specification for performance K-series engine builds, ensuring a secure fit for the valve springs and locks.

Are these retainers compatible with single valve springs?

These Ferrea retainers are specifically designed to work with double valve springs. Using them with single springs may not provide the correct fit or function.
