What is the purpose of a valve lock?

Valve locks, also known as keepers, secure the valve spring retainer to the valve stem. They are critical for keeping the valvetrain components connected and functioning correctly under engine load.

What does the .3110 size refer to?

The .3110 size indicates the diameter of the valve stem that these locks are designed to fit. It's important to match this size to your specific valve stems for a secure fit.

Why is the 10-degree angle important?

The 10-degree angle on the keeper must match the angle of the valve spring retainer. This precise match ensures the retainer sits securely and prevents the valve lock from dislodging, which is vital for engine reliability.

About this part

Product Details

This is a set of eight Manley 10 Degree .3110 Bead Valve Locks. These keepers are essential components for your engine's valvetrain, working to secure the valve spring retainers to the valve stem. They ensure that the valvetrain components stay properly connected under the high stresses of engine operation.

Manley is known for making well-built engine parts, and these valve locks are no exception. The .3110 size is specific for certain valve stem diameters, and the 10-degree angle on the keeper is designed to match the angle of the valve spring retainer. This precise fit is crucial for preventing valve float and ensuring consistent valve operation, especially in performance applications where valve control is critical.

When rebuilding or modifying an engine, using reliable valve locks like these from Manley is important for the longevity and performance of your valvetrain. Always ensure you have the correct size and angle to match your specific valve springs and retainers for optimal performance.
