What is the purpose of valve locks?

Valve locks, also known as keepers, 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 and in place, ensuring the valve operates correctly.

What does the '7 Degree' refer to on these valve locks?

The '7 Degree' refers to the angle of the taper on the valve lock. This angle matches the angle of the valve spring retainer groove, creating a secure fit to hold the valve spring assembly together.

What does 'Machined Bead' mean for these valve locks?

The machined bead is a small raised feature on the valve lock that helps it bite into the valve stem groove. This provides a more secure grip compared to locks without this feature, reducing the chance of them coming loose.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these 7-degree valve locks are a good example of that. They are designed to hold your valve springs securely in place, ensuring your valve train operates as it should. This set includes 16 pieces, enough for a typical 4-cylinder engine.

These valve locks feature a machined bead, which helps them grip the valve stem and keeper groove more effectively. The 7-degree angle is a common specification for many performance and OEM applications, ensuring a solid lock-up. Using well-made valve locks is important for maintaining consistent valve timing and preventing catastrophic engine failure.
