What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or valve collets, 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 together and keep the valve seated properly.

What does the 'bead' design mean?

The bead design refers to a small ridge or protrusion on the keeper. This feature helps to create a tighter, more secure fit with the valve spring retainer, reducing the likelihood of the keeper backing out due to vibration or engine stress.

Are these keepers sold individually or as a set?

This product is sold as a set. The exact quantity included in the set is typically enough for a full engine, but it's always best to confirm the package contents if you need a specific number.
