What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or retainers, work with the valve spring to hold the valve securely in place. They prevent the valve from moving out of position during engine operation, ensuring proper sealing and preventing damage to the valvetrain.

What does the '10 DEG' and '.3715 BEAD' mean on these keepers?

The '10 DEG' refers to the 10-degree angle of the bead on the keeper, which is designed to lock into a matching angle on the valve spring retainer. The '.3715 BEAD' indicates the specific diameter or size of the bead, which is crucial for ensuring a precise and secure fit with compatible valve stems and retainers.

Are these keepers sold individually or as a set?

This product is sold as a set of Manley Valve Lock/Keepers, model LOC-10 DEG .3715 BEAD LocCap, providing the necessary components for your engine build.

These Manley keepers offer a solid option for ensuring your valvetrain is assembled correctly and will hold up under demanding conditions. Always refer to your engine's service manual or a trusted build guide for the correct installation procedure and compatibility with your specific valve springs and retainers.
