What type of valve locks are needed for these Manley retainers?

These Manley 7 Degree retainers require 7-degree valve locks. You can use Manley's P/N 13098 valve locks or the factory Chevrolet LS valve locks.

What is the main benefit of using titanium retainers?

Titanium retainers are significantly lighter than stock steel retainers. This reduction in valvetrain mass allows the engine to achieve higher RPMs more safely and reliably, improving overall performance potential.

Are these retainers compatible with all valve stem diameters?

No, these specific retainers are designed for valves with an 8mm stem diameter. They also feature a standard installation height.

About this part

Product Details

If you're working on the valvetrain of your 1985-2004 Chevrolet Corvette, these 7 Degree Titanium Retainers from Manley Performance are a solid option. They're designed to reduce the overall weight of your valvetrain components, which is crucial for allowing your engine to safely rev higher and more reliably. This is especially important if you're rebuilding the top end or looking for improved performance.

Manley uses a special 6AL-4V titanium alloy for these retainers, making them incredibly strong while also being very lightweight. Each retainer weighs only about 5.0 grams, and they're CAD designed to shave off as much mass as possible without compromising their ability to hold up under pressure. They are made to fit valves with an 8mm stem diameter and are designed for a standard installation height. You'll need to use 7-degree valve locks with these retainers; Manley recommends their own P/N 13098 or factory Chevrolet LS valve locks.
