What type of valve locks do these retainers use?

These Manley retainers are designed to work with 7-degree valve locks. You will need to use either Manley's recommended part number 13098 or the factory Chevrolet LT valve locks.

What is the benefit of using titanium retainers?

Titanium retainers are chosen for their high strength-to-weight ratio. This means they are very strong but also significantly lighter than steel retainers, which helps reduce valvetrain mass. This can lead to improved RPM potential and better valve control at high engine speeds.

How does the installed height compare to other retainers?

These retainers offer a +.105 inch advantage in installed height compared to some other options. This extra height can be beneficial when setting up your valve springs to achieve the correct installed height for optimal performance.

About this part

Product Details

Manley Performance is known for making strong, reliable engine components, and these titanium valve spring retainers are a great example of that. If you're working on an LT4 engine and looking to get the most out of your valvetrain, these retainers are designed to help you achieve higher RPMs. They're made from special 6AL-4V titanium, which is chosen for its excellent strength while keeping the weight down. This reduction in mass is important because it helps the valvetrain spin faster and more reliably at high engine speeds.

These retainers are CAD designed to minimize weight without compromising their ability to handle the forces involved. They are specifically made to work with 7-degree valve locks, and you'll need to use either Manley's recommended part number 13098 or the factory Chevrolet LT valve locks. Keep in mind that these are the same dimensions as the 23628 retainers but are made from titanium for a lighter, stronger option. They offer a +.105 inch advantage in installed height compared to some other options, which can be crucial for getting your valve spring setup just right.
