What is the purpose of a valve spring shim?

A valve spring shim is used to make small adjustments to the installed height of a valve spring. This is important for ensuring the valve train operates correctly and the spring isn't over or under-stressed.

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

This means the shim is 0.030 inches thinner than a standard or full-size shim. This specific measurement is used when a slight reduction in installed spring height is needed.

What material is this valve spring shim made from?

This valve spring shim is constructed from durable steel, designed to handle the demanding environment within an engine.

About this part

Product Details

Manley Performance offers this valve spring shim, measuring .030 inches undersize. When you're rebuilding or modifying an engine, getting the valve spring installed at the correct height is critical for proper valve train function and performance. Sometimes, factory specifications or aftermarket camshafts require slight adjustments to achieve the ideal installed height. This shim is designed to provide that precise adjustment, ensuring your valve springs are seated correctly for optimal operation.

This shim is made from durable steel, built to withstand the pressures and temperatures within the engine. Its .030 inch undersize dimension is a specific measurement that mechanics often need for fine-tuning valve spring installations, especially when dealing with variations in valve lengths or spring seat depths. Using the correct shim helps prevent issues like valve float or excessive spring stress, contributing to the longevity and reliability of your engine's top end.
