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 hold the valve spring assembly in place, ensuring the valve operates correctly.

What does the 7-degree angle mean for these valve locks?

The 7-degree angle refers to the taper on the valve lock that mates with the valve spring retainer. This specific angle is designed to create a secure and stable connection, preventing the retainer from slipping off under engine operation.

Are these valve locks compatible with all Chevy LS engines?

These valve locks are specifically designed for Chevy LS engines and feature an 8.0mm stem size with a 7-degree keeper angle. It's always best to verify the specific requirements for your engine build to ensure proper fitment.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these 8.0mm Single Radius Valve Locks are a prime example. They are designed to work with Chevy LS engines and are crucial for keeping your valve springs properly seated. Without these, your valves wouldn't operate correctly, and your engine wouldn't run.

These valve locks are machined with a 7-degree angle and are sized at 5/16 inch, with a +.050 inch offset. This specific sizing and angle are important for ensuring a secure fit with the valve stem and the valve spring retainer. They are sold in pairs, and you get 16 pairs in this set, which is enough for a complete 8-cylinder engine.
