Ferrea Double Spring Pro CNC Super 7 Deg Titanium Retainer - Set of 16

Ferrea is well-known for making high-performance valvetrain components, and this set of 16 Double Spring Pro CNC Super 7 Degree Titanium Retainers is a prime example of their work. These retainers are specifically designed to work with dual valve springs, offering the support needed for aggressive camshaft profiles and high RPM operation. The 7-degree lock angle ensures a secure fit with compatible valve keepers, preventing any unwanted movement under extreme stress.

What sets these retainers apart is the material and manufacturing process. They are CNC machined from aerospace-grade titanium, which is not only incredibly strong but also significantly lighter than steel. This reduction in mass up top helps the valve train operate more efficiently and reduces stress on the valve guides and springs. The 'Super' designation often indicates a design optimized for even greater durability and performance in demanding applications. Each retainer is precisely machined to ensure a perfect fit with the valve stem and the valve spring, which is crucial for consistent valve operation and sealing.

This set includes 16 retainers, enough for a typical V8 engine. When building a high-performance engine, especially one that will see frequent track use or aggressive street driving, components like these retainers are critical for reliability and achieving maximum performance. They are designed to handle the increased forces and speeds associated with performance camshafts and higher spring pressures. Ensure you have the correct 7-degree valve keepers to match these retainers for a secure and effective installation.
