What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve collets, work with the valve spring retainer to hold the valve in place. They are crucial for keeping the valve train properly assembled and functioning, especially under high engine speeds.

What does the '-050' in the part description mean?

The '-050' indicates that these keepers are 0.050 inches undersize compared to a standard size. This is often used when rebuilding engines to account for wear on the valve stems or to achieve a specific fit with aftermarket valve stems.

Are these keepers compatible with other brands of valve springs and retainers?

While these keepers are designed to work with Manley valve locks, compatibility with other brands can vary. It's always best to consult the manufacturer's specifications or a trusted mechanic to ensure they will work with your specific valve spring and retainer setup.

About this part

Product Details

These Manley valve lock keepers are machined to a precise 7-degree angle and measure 0.3135 inches in diameter. They are also 0.050 inches undersize, which is important for ensuring a snug fit with your valve stems during engine rebuilds or performance builds. Getting the right lock and keeper combination is critical for proper valve train function, preventing valve float and ensuring your engine runs smoothly and reliably.

Manley is known for making solid engine components, and these keepers are no exception. They are well-built to handle the stresses of engine operation. When you're putting an engine back together, especially if you're working on the cylinder heads, having reliable valve keepers is essential. These are designed to work with Manley's other valve train components, ensuring a matched system.
