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, ensuring the valve stays properly seated when not in operation.

How many keepers are included in this set?

This set from Manley Performance includes 8 valve lock keepers. This is typically enough for a standard 4-cylinder engine's intake and exhaust valves, but you should confirm your engine's specific needs.

What material are these valve lock keepers made from?

While the specific material composition isn't detailed, Manley Performance is known for producing robust internal engine components. These keepers are manufactured to meet the demands of engine operation.
