What material is this valve spring retainer made from?

This valve spring retainer is made from titanium. Titanium is chosen for its strength and lightweight properties, which can help reduce valvetrain mass.

What does the 7-degree lock angle mean?

The 7-degree lock angle refers to the angle of the groove where the valve keepers (locks) seat. This specific angle is designed to mate with compatible valve keepers to securely hold the valve spring in place.

Do I need to buy multiple retainers for my engine?

Yes, this retainer is sold individually. You will need to purchase one retainer for each valve in your engine's cylinder head, so be sure to order the correct quantity for your specific application.

About this part

Product Details

This Ferrea valve spring retainer is CNC machined from titanium, a strong yet lightweight material that helps reduce overall valvetrain mass. The 7-degree lock angle is designed to work with specific valve locks, ensuring a secure fit for the valve spring assembly. This retainer is a single component, intended for use in rebuilding or upgrading the valvetrain on a Mitsubishi 4B11T engine.

Using titanium for the retainer offers a notable advantage by decreasing the reciprocating weight in the valvetrain. Less weight means the valvetrain can operate more reliably at higher RPMs, which is crucial for performance applications. The precision CNC machining ensures that each retainer meets tight tolerances, contributing to consistent valve operation and sealing. This part is sold individually, so you'll need to order the correct quantity for your engine's cylinder head.
