What material is this valve spring retainer made from?

This Ferrea valve spring retainer is machined from solid titanium. Titanium is chosen for its lightweight properties, which can help reduce the overall mass of the valve train.

What is the purpose of the 7-degree lock angle?

The 7-degree lock angle on this retainer is designed to securely hold the valve keepers in place. This ensures the valve spring stays properly seated during engine operation.

Is this retainer sold individually or as a set?

This Ferrea retainer is sold as a single unit. You will need to purchase the appropriate number of retainers, springs, and keepers for your specific engine build.

About this part

Product Details

Machined from solid titanium, this Ferrea valve spring retainer for the Subaru FA20 engine is designed to be exceptionally lightweight. The 7-degree lock angle ensures a secure fit for your valve springs, and the CNC machining process means precise dimensions for consistent performance. This retainer is a single unit, intended for use with a matching valve spring and keeper setup.

Using titanium here isn't just about saving a few grams; it's about reducing the overall mass that the valve train has to manage. Less mass means the valve train can operate more reliably at higher RPMs, and it can help improve the responsiveness of the engine. This part is a direct replacement for the stock retainer, making it a straightforward upgrade if you're working on the cylinder heads.
