What is the purpose of valve lock/keepers?

Valve lock keepers, also known as valve locks, 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, keeping the valve seated properly.

What does the '+.050' sizing mean for these keepers?

The '+.050' indicates that these keepers are designed for valve stems that have been machined or are already 0.050 inches larger in diameter than a standard valve stem. This ensures a precise fit in modified or performance engine builds.

Are these keepers sold individually or as a set?

This product is sold as a set, providing the necessary keepers for your valve train assembly. Please refer to the product details for the exact quantity included in the set.
