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

If you're rebuilding the top end of your engine, especially for high-performance applications where valve control is critical, you'll want to pay close attention to the valve retainers. These Ferrea Double Spring Pro CNC Super retainers are made from titanium, which is significantly lighter than steel. This reduced mass at the top of the valve train helps to lower the overall reciprocating weight, allowing the engine to rev more freely and reducing stress on the valvetrain components at high RPMs.

Ferrea machines these retainers using a CNC process for precise dimensions, ensuring they seat properly on the valve springs. The 'Super 7 Deg' designation refers to the angle of the retainer's seat, which is designed to work with specific valve springs and locks to maintain secure valve control. This set includes 16 retainers, enough for a typical 8-cylinder engine. Using titanium retainers is a common upgrade when building engines for racing or extreme street performance, where every ounce of weight savings and every bit of valvetrain stability matters.

When installing these retainers, it's important to use the correct valve spring locators and valve locks that are compatible with the 7-degree angle. Ferrea makes a wide range of valvetrain components, and ensuring all parts are matched will give you the best performance and reliability. This is a well-built component for serious engine builds.
