What is the purpose of a valve lock?

Valve locks, also called keepers, are small but essential parts that secure the valve spring retainer to the valve stem. They prevent the valve from falling into the cylinder during operation.

What does the 10-degree angle mean?

The 10-degree angle refers to the taper of the valve lock. This angle is designed to match the taper on the valve spring retainer, creating a secure and stable connection to hold the valve spring assembly in place.

What size valve stem do these locks fit?

These Manley valve locks are specifically designed to fit valve stems with a diameter of .3415 inches. It's important to match this size to your valve stems for a proper fit.
