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 keep the valve spring compressed and the valve seated properly.

What does the '+0.50 Inch' designation mean?

The '+0.50 Inch' indicates that these valve locks are 0.00050 inches undersize compared to a standard size. This undersize helps ensure a very snug and secure fit within the valve stem grooves.

Are these suitable for all engine builds?

These are conventional groove type valve locks, making them suitable for many engine builds. However, always confirm that the 10-degree angle and .3110 groove size match your specific valve spring retainers and valve stems.
