What is the primary benefit of using titanium retainers?

Titanium retainers are significantly lighter than steel ones. This reduction in rotational mass at the top of the valve train can lead to improved valve control and a more responsive engine, especially at higher RPMs.

What does the 7-degree lock angle mean for my build?

The 7-degree lock angle refers to the angle of the groove where the valve keeper locks into the retainer. This specific angle is designed to work with valve springs that also feature a matching angle, ensuring a secure and proper fit for the valve train components.

Are these retainers compatible with stock valve springs?

These retainers are designed for use with double valve springs, often found in performance applications. It's important to ensure your valve springs have a compatible 7-degree lock angle for proper installation and function.

About this part

Product Details

Starting with a 7-degree lock angle, these Ferrea Pro CNC Titanium Retainers are specifically made for the Mitsubishi 4B11T engine. They are designed to work with double valve springs, which are often used in performance builds to handle higher RPMs and more aggressive camshaft profiles. The titanium construction makes them notably lightweight, reducing rotational mass at the top of the valve train. This can lead to improved valve control and a more responsive engine, especially when you're pushing the limits.

Each retainer is CNC machined for precise dimensions, ensuring a consistent fit with your valve springs and locks. This level of accuracy is important for proper valve seating and preventing valve float at high engine speeds. Ferrea is well-known for making strong valvetrain components, and these retainers are built to withstand the demands of a performance-tuned 4B11T engine. They are sold as a set of 16, covering all the valves for your engine.
