What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or retainers, are small components that fit into a groove on the valve stem. They work with the valve spring retainer to keep the valve spring compressed, holding the valve in its closed position.

What does the '10 degree bead lock' refer to?

The 10-degree bead lock design refers to the angle of the keeper and the small bead or ridge on it. This design helps the keeper seat more securely into the matching angle on the valve spring retainer, preventing it from coming loose under engine vibration or stress.

Are these keepers compatible with all valve springs?

These keepers are specifically designed for 7mm valve stems and a 10-degree retainer angle. You should confirm that your valve springs and retainers match these specifications for proper fitment and function.
