What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or 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 falling into the cylinder.

What does the 'bead coated' finish mean for these keepers?

The bead coating is a surface treatment applied to the keepers. This coating is designed to reduce friction and wear at the contact points between the keeper, the valve stem, and the valve spring retainer, potentially improving durability.

What does the '10 DEG' specification refer to?

The '10 DEG' refers to the angle of the lock mechanism on the keeper. This angle is designed to mate with a corresponding angle on the valve spring retainer, ensuring a secure and precise fit to hold the valve train components together.
