What material are these retainers made from?

These retainers are CNC machined from titanium. This material is chosen for its strength and lightweight properties, which can be beneficial in high-performance engine builds.

What is the purpose of a double spring retainer?

Double spring retainers are used with dual valve springs. This setup is typically employed in performance applications to provide increased spring pressure, which helps prevent valve float at higher engine speeds.

What does the 7-degree lock angle refer to?

The 7-degree lock angle refers to the angle of the groove where the valve keepers (locks) engage with the retainer. This specific angle is designed to ensure a secure and proper fit with compatible valve keepers.

About this part

Product Details

Ferrea is well-known for making high-performance valvetrain components, and this set of 16 double spring titanium retainers for the Mitsubishi 4B11T engine is a prime example of their work. These retainers are designed to handle the demands of performance builds where increased RPMs and spring pressures are common.

Each retainer is CNC machined from titanium, which offers a strong yet lightweight option for your valvetrain. This material choice helps reduce overall weight in the valvetrain assembly, which can be beneficial at higher engine speeds. The 7-degree lock angle ensures a secure fit with your valve springs, and the double spring design is intended for applications requiring more aggressive spring rates to control valve float.

This set includes all 16 retainers needed for a complete engine installation. If you're rebuilding the top end of your 4B11T for performance, these retainers are a solid option to consider for their material strength and precise machining.
