What is the benefit of using titanium retainers?

Titanium retainers are chosen for their strength and low weight. This helps to reduce the overall mass in the valvetrain, which can lead to improved engine response and better control of the valves at high engine speeds.

What does '7 Deg Pro CNC' refer to?

This refers to the angle of the groove where the valve locks seat, which is 7 degrees. The 'Pro CNC' indicates that the retainers are precisely machined using computer numerical control (CNC) for accuracy and a secure fit with the valve locks.

Are these retainers compatible with stock valve springs?

These retainers are specifically designed for use with double valve springs. Using them with single or stock valve springs may not provide the intended performance benefits and could lead to improper function.

Product Details

If you're building out the top end of your Subaru FA20 engine, especially for performance applications, you'll want to pay close attention to your valve springs and retainers. These Ferrea titanium retainers are designed to work with double valve springs, offering a solid foundation for high-RPM operation. They are CNC machined from titanium, which makes them strong and lightweight, helping to reduce valve float when the engine is really working.

The 7-degree lock groove is a specific detail that ensures a secure fit with your valve locks, preventing any unwanted movement. This attention to detail in the machining process means you get a well-built component that can handle the stresses of an upgraded engine. Using titanium also helps to keep overall valvetrain weight down, which can contribute to improved engine response.

This set includes 16 retainers, enough for a complete engine build. When installing, ensure you're using compatible double valve springs and that all components are properly seated according to your engine build specifications.
