What is the purpose of a valve spring shim?

Valve spring shims are used to adjust the installed height of the valve spring. This ensures the spring is seated correctly and provides the intended pressure, which is important for valve train stability and performance.

What material are these shims made from?

These shims are made from a solid material designed to withstand the pressures and conditions within the engine's cylinder head.

How do I know if I need a .015 inch shim?

You'll need to measure the installed height of your valve springs. If the measurement is too tall, a shim can be used to reduce the installed height to the manufacturer's specification.

Product Details

When you're rebuilding the top end of your engine, getting the valve spring installed height just right is critical for proper valve train function. These valve spring shims from Manley Performance are designed to help you achieve that precise height. They're made from a solid material that can handle the pressures within the cylinder head.

This particular shim measures .015 inches thick. You'll use these to fine-tune the installed height of your valve springs, ensuring they're seated correctly and providing the intended pressure.
