About this part

Product Details

Manley Performance has a solid reputation for building tough engine parts, and this titanium valve spring retainer is no exception. If you're working on an LS1 or LT4 engine and looking to get more out of your valvetrain, this part is designed to help. It's made from special 6AL-4V titanium, which is incredibly strong but also very light. This means it helps reduce the overall weight of your valvetrain components. Less weight spinning around up there means your engine can potentially rev higher and more reliably.

These retainers are designed using computer modeling and then CNC machined to make sure they're exactly right. The goal is to shave off as much weight as possible without compromising strength, giving you better control over your valves, especially at higher engine speeds. Keep in mind that you'll need to use 7-degree valve locks with this retainer, and Manley recommends their own part number 13098 or the factory Chevrolet LS valve locks.
