What is the benefit of using a titanium retainer?

Titanium retainers are lighter than steel ones. This reduced mass in the valvetrain allows components to react faster to camshaft changes, especially at high engine speeds.

What does the '6 Deg Pro CNC' designation mean?

This refers to the 6-degree angle machined into the retainer, which is specific to certain Subaru EJ20 cylinder head designs. The 'Pro CNC' indicates it's made using precision computer numerical control machining.

Does this retainer come with other parts?

This listing is for a single retainer unit. It is designed to be used with compatible double valve springs and other valvetrain components, which are sold separately.

Product Details

This Ferrea retainer is CNC-machined from titanium, a material chosen for its strength and low weight, which is important for high-revving engines like the Subaru EJ20. It's designed to work with double valve springs and features a 6-degree angle, specifically suited for certain EJ20 cylinder heads. Using a titanium retainer helps reduce the overall mass of the valvetrain components, allowing them to respond more quickly to camshaft commands, especially at higher RPMs. This can lead to improved valve control and engine performance when you're pushing the limits.

Ferrea is known for making solid valvetrain components, and this retainer is no exception. The precision CNC machining ensures it fits right with your valve springs and seals, which is critical for proper engine function and preventing leaks. While this is a single retainer, it's part of a system designed to handle the demands of performance Subaru engines. If you're rebuilding or upgrading your EJ20's top end, components like these are key to achieving reliable power.
