What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve collets, are small components that fit into a groove on the valve stem. They work with the valve spring retainer to keep the valve spring assembly securely attached to the valve, preventing the valve from dislodging during operation.

What does '.3110 +.050 B/L' mean for these keepers?

This indicates the nominal size of the keeper is .3110 inches, and they are machined to be 0.050 inches undersize. This means they are intended for valve stems that are slightly smaller than the nominal size, ensuring a snug fit.

Are these keepers sold individually or as a set?

Valve lock keepers are typically sold in sets for a complete engine or cylinder head. Please check the product details or contact us to confirm the exact quantity included in this part number.
