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 securely in place, ensuring the valve operates correctly.

What does the '.3085 bead' and '10 degree' refer to?

The '.3085 bead' refers to the specific diameter and shape of the groove or ridge on the keeper that engages with the valve spring retainer. The '10 degree' specifies the angle of the taper on the keeper, which must match the angle of the retainer for a proper fit.

Are these keepers sold individually or as a set?

The provided product information indicates this is for a specific part number, typically sold in sets. Please check the product listing details or contact customer support for the exact quantity included per package.
