What is the purpose of a valve spring shim?

Valve spring shims are used to adjust the installed height of the valve springs. This is important for ensuring the springs are operating within their designed pressure range and for proper valve train geometry, especially when using aftermarket camshafts.

What material are these shims made from?

These shims are made from durable steel, which provides a solid and stable base for the valve spring.

How do I know if I need a .060 inch thick shim?

The need for a specific shim thickness depends on your valve spring installed height measurement and the specifications required by your camshaft and cylinder heads. You'll need to measure your installed height and compare it to the manufacturer's recommended range.

About this part

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 geometry and performance. These shims from Manley Performance are designed to help you achieve that precise height. They are made from durable steel and are precisely machined to ensure they sit flat against the spring seat.

This particular shim measures 1.625 inches in diameter and is 0.060 inches thick. Using shims allows you to make small adjustments to the installed height of your valve springs, which can be important for cam compatibility and ensuring the springs operate within their intended range. It's a small part, but it plays a big role in the overall health and performance of your engine's valvetrain.
