What is the primary function of a valve spring retainer?

A valve spring retainer holds the valve spring compressed, ensuring the valve closes securely against the valve seat. It's a key component in the valvetrain's ability to manage valve timing.

Why is titanium used for this retainer?

Titanium is chosen for its high strength-to-weight ratio. Using a lighter retainer can help reduce the mass in the valvetrain, which can improve its ability to operate reliably at higher engine speeds.

What does 'Pro CNC' mean for this part?

'Pro CNC' indicates that the retainer has been machined using Computer Numerical Control (CNC) equipment. This process allows for high precision and consistency in the part's dimensions and finish, which is important for proper valvetrain function.

About this part

Product Details

When you're rebuilding the top end of your Subaru STI, especially if you're aiming for improved performance, the valve spring retainers play a critical role. This Ferrea retainer is made from titanium, which is a strong yet lightweight material that helps reduce overall valvetrain mass. This can lead to better responsiveness at higher RPMs. The 'Pro CNC' designation means it's machined with precision for a consistent fit and finish, which is important for reliable operation.

Ferrea is known for making well-built valvetrain components, and this retainer is designed to work with specific valve springs to ensure your engine's valves open and close correctly. Its design is intended to handle the stresses of performance applications, helping to keep your valvetrain stable.
