What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or retainers, are small components that fit into a groove on the valve stem. They work with the valve spring retainer to hold the valve spring assembly securely to the cylinder head, ensuring proper valve operation.

What does the '10 DEG' and '.3415 BEAD' specification mean?

The '10 DEG' refers to the angle of the keeper, which is designed to match the angle of the valve spring retainer it will interface with. The '.3415 BEAD' indicates the specific size of the groove or bead on the valve stem that these keepers are designed to fit into.

Are these keepers sold individually or as a set?

These are typically sold in sets, as you need multiple keepers for all the valves in an engine. Please check the product details to confirm the exact quantity included in this package.
