What material are these Manley valve spring retainers made from?

These retainers are made from 6AL-4V titanium. This material is chosen for its high strength-to-weight ratio, helping to reduce the overall mass in the valvetrain.

What type of valve locks do I need to use with these retainers?

You must use 7-degree valve locks with these retainers. Manley recommends their P/N 13098 or factory Chevrolet LS valve locks for proper installation and function.

What is the benefit of using titanium retainers?

Titanium retainers help reduce the mass at the top of the valve stem. This can lead to improved RPM potential and more stable valve control in high-performance engine applications.

About this part

Product Details

These Manley valve spring retainers are made from 6AL-4V titanium, a strong and lightweight material chosen to help reduce the overall mass in your valvetrain. CNC machining to tight tolerances means they fit precisely, which is crucial for consistent valve control, especially when you're pushing your engine to higher RPMs. They're designed to work with 7-degree valve locks and are specifically intended for LS engines, often used in performance builds where every bit of weight savings and improved valvetrain stability matters.

Using titanium helps lower the rotational mass at the top of the valve stem, allowing your valvetrain to handle higher engine speeds more reliably. This particular retainer has a 1.155-inch outer diameter and is designed for a standard installation height, fitting 8mm valve stems. It's important to note that these retainers require specific 7-degree valve locks, and Manley recommends using their own part number 13098 or the factory Chevrolet LS valve locks for proper setup.
