What is the purpose of valve locks?

Valve locks, also known as keepers, are small components that fit into grooves on the valve stem. They work with the valve spring retainer to hold the valve spring assembly together, ensuring the valve stays properly seated and operates correctly.

What does the '+.050' designation mean?

The '+.050' indicates that these valve locks have an additional 0.050 inches of clearance compared to a standard fit. This can be important for specific valve spring and retainer combinations to ensure proper seating and function.

Are these locks sold individually or as a set?

This product is sold as a set of eight valve locks, which is typically enough for a standard four-cylinder engine's intake and exhaust valves.
