What is the purpose of a valve spring shim?

A valve spring shim is used to adjust the installed height of a valve spring. This adjustment is crucial for ensuring the spring is operating within its designed pressure range, which affects valve train performance and reliability.

What does '.030 undersize' mean for this shim?

'.030 undersize' indicates that the shim is slightly smaller than a standard size. This is used to achieve a specific installed height when the standard shim is not sufficient.

What material is this shim made from?

This shim is made from a solid material suitable for the high-pressure and temperature environment within an engine's cylinder head, designed to withstand the demands of valve train operation.

About this part

Product Details

What you get with this Manley Performance part is a single valve spring shim, measuring 1.625 inches in diameter and .030 inches undersize. This shim is used to adjust valve spring installed height, which is a critical measurement when rebuilding or modifying an engine's cylinder head. Getting the installed height correct ensures the valve springs are operating within their intended pressure range, which is key for proper valve train function and engine reliability.

This shim is made from a solid material designed to withstand the pressures and temperatures found in the cylinder head. By adding or removing shims, you can fine-tune the preload on your valve springs. This is especially important if you're using aftermarket camshafts or cylinder heads that might have slightly different dimensions than stock components. It’s a small part, but it plays a big role in making sure your valve springs perform as they should.
