What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or collets, are small components that fit into a groove on the valve stem. They work with the valve spring retainer to hold the valve securely in place within the cylinder head, ensuring proper valve operation.

What does the '+.050 B/L' designation mean?

This designation indicates that these keepers are 0.050 inches larger in diameter than a standard keeper. This sizing is typically used when the valve stem itself is also larger than stock, often after valve seat work or when using aftermarket valves.

Are these keepers compatible with all valve springs and retainers?

These keepers are designed to work with specific Manley valve springs and retainers, and potentially other compatible aftermarket components. It's crucial to ensure they match the groove on your valve stem and the retainer design for a secure and correct fit.

About this part

Product Details

These are Manley Valve Lock/Keeper sets, specifically the LOC-TI CAPT.3415 model, which are +.050 inch larger in diameter. They are designed for engine component applications where precise valve control is critical. When you're rebuilding an engine, especially a performance build, the valve train components need to be just right. These keepers work with the valve springs and retainers to securely hold the valve in place, ensuring proper timing and preventing any unwanted movement.

Manley is known for making well-built performance engine parts, and these keepers are no exception. They are made from strong materials designed to withstand the high stresses and temperatures found in an engine's cylinder head. The +.050 sizing indicates they are intended for applications where the valve stem diameter is slightly larger than standard, often seen after valve jobs or when using specific aftermarket valves. It's important to match the keeper size to your valve stem diameter for a secure fit and optimal performance.
