What valve springs are compatible with these retainers?

These Ferrea 7 Degree CNC Super retainers are designed to be used with specific Ferrea valve springs, including part numbers S10004, S10023, and S11004. It is important to use the correct spring to ensure proper fitment and performance.

Why is titanium used for these retainers?

Titanium is used for its excellent strength-to-weight ratio. This means the retainers are strong enough to handle high spring pressures and engine speeds while contributing less mass to the valvetrain, which can improve overall engine response.

What does the '7 Degree CNC Super' designation mean?

The '7 Degree' refers to the angle of the retainer, which is designed to match specific valve spring configurations for optimal seating. 'CNC Super' indicates that the retainers are precisely machined using Computer Numerical Control (CNC) technology for accuracy and a high-quality finish.

Product Details

Machined from solid titanium, these Ferrea 7 Degree CNC Super retainers are built for high-performance engine builds where valve control is critical. The 7-degree angle is specifically designed to match certain valve spring configurations, ensuring proper seating and preventing valve float at high RPMs. This set includes 16 retainers, enough for a complete V8 engine.

Ferrea is known for making well-built valvetrain components, and these retainers are no exception. The CNC machining process allows for precise dimensions and a smooth finish, which is important for reducing friction and wear on the valve stem and spring. Titanium is chosen for its strength-to-weight ratio, meaning these retainers are strong enough to handle the forces of aggressive camshafts and high spring pressures while keeping overall valvetrain mass down. This can lead to improved engine response and durability under demanding conditions.

These retainers are intended for use with specific Ferrea valve springs, namely the S10004, S10023, or S11004 models. Make sure you have the correct spring part numbers before ordering to ensure proper compatibility. Proper installation is key for valvetrain longevity, so refer to the manufacturer's installation instructions for details on seating and assembly.
