What type of valve locks do these retainers require?

These Manley retainers are designed to be used with 7-degree valve locks. You'll need to use either Manley's P/N 13098 valve locks or the factory Chevrolet LS valve locks.

What is the main benefit of using titanium retainers?

The primary benefit of using titanium retainers is the significant reduction in valvetrain mass. This lighter weight allows the engine to achieve higher RPMs more easily and helps maintain better valve control.

Are these retainers compatible with all valve stem sizes?

No, these specific retainers are designed for 8mm valve stems. It's important to verify your valve stem diameter before purchasing.

About this part

Product Details

Crafted from 6AL-4V titanium, these Manley valve spring retainers are designed to significantly reduce valvetrain mass. This is a notable advantage when you're aiming for higher RPMs, as less rotating mass helps the engine rev more freely and reliably. The material choice here is key; titanium offers a strong yet lightweight solution that's crucial for performance builds.

These retainers are CNC machined to tight tolerances, ensuring they work precisely with your valve springs and locks. They are specifically designed to work with 7-degree valve locks and are compatible with Manley's own P/N 13098 or factory Chevrolet LS valve locks, which are designed for 8mm valve stems. The standard installation height means they should integrate smoothly into many existing setups, helping to maintain proper valve control even under demanding conditions.
