What material are these valve spring retainers made from?

These Ferrea valve spring retainers are made from aerospace-grade titanium. This material is chosen for its strength and lightweight properties, which are beneficial for high-performance engine builds.

What is the purpose of CNC machining for these retainers?

CNC machining ensures that each retainer is manufactured to exact tolerances. This precision is important for a secure fit with the valve spring and valve stem, contributing to reliable valve train operation.

Are these retainers compatible with dual valve springs?

No, these Ferrea E11139 retainers are specifically designed for single valve springs. They feature a 7-degree lock angle, which is standard for many single spring setups.

About this part

Product Details

Crafted from aerospace-grade titanium, these Ferrea E11139 valve spring retainers are CNC machined for exact tolerances, a critical detail for high-performance VW 2.0T engines. They are designed to work with single valve springs and feature a 7-degree lock angle, ensuring a secure and reliable connection between the valve spring and the valve stem. This set includes eight retainers, enough for a full engine build.

Using titanium for the retainers significantly reduces weight compared to steel, which helps to decrease valve train mass. This lower mass means less inertia, allowing the valve train to operate more freely at higher RPMs. The precise CNC machining ensures that each retainer fits perfectly, preventing any potential issues that could arise from inconsistent parts. This attention to detail is what makes Ferrea a popular choice for engine builders looking for dependable components.
