What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or 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 securely onto the valve, preventing the valve from coming loose.

What material are these Manley valve lock keepers made from?

These valve lock keepers are stamped from steel. This material is chosen for its strength and ability to withstand the high stresses and temperatures found within an engine's cylinder head.

Are these keepers a direct replacement for all engines?

These keepers are specifically designed for 11/32 inch valve stems, which is a common size. However, it's always best to verify your specific engine's valve stem diameter and consult your vehicle's service manual to ensure compatibility before installation.
