What specific valve locks are needed for these retainers?

These Manley Titanium Valve Spring Retainers are designed for 7-degree valve locks. Manley recommends using their part number 13098, but factory Chevrolet LT4 valve locks are also compatible.

What is the benefit of using titanium retainers?

Titanium retainers are significantly lighter than steel ones. This reduced mass in the valvetrain allows the engine to rev higher and more freely, improving overall performance and ensuring better valve control at high RPMs.

How do these retainers differ from standard ones?

These retainers are made from 6AL-4V titanium and are CAD designed to minimize weight without sacrificing strength. They also offer an extra .095 inches of installed height, which can be beneficial for tuning spring pressures in specific engine builds.

About this part

Product Details

This product includes a set of Manley Titanium Valve Spring Retainers, specifically designed for LT4 engines with 8mm valve stems. These retainers are crucial components in your valvetrain, working with the valve springs to control the opening and closing of your engine's valves. By using special 6AL-4V titanium, Manley has created a part that's both incredibly strong and remarkably lightweight, which is key for high-RPM engine operation.

The design process involved CAD and finite element analysis to shave off as much mass as possible without compromising strength. This reduction in valvetrain weight helps your engine rev more freely and ensures better valve control, especially when you're pushing the engine hard. It's important to note that these retainers require specific 7-degree valve locks; Manley recommends their own P/N 13098, though factory Chevrolet LT4 locks can also be used. These retainers offer an additional .095 inches of installed height compared to some other options, which can be important for achieving the correct spring pressure in your build.
