What is the purpose of a valve spring seat?

A valve spring seat sits between the valve spring and the cylinder head. Its main job is to provide a stable base for the spring, ensuring it's properly aligned and supported. This helps maintain the correct installed height and pressure of the valve spring.

What material are these valve spring seats made from?

These valve spring seats are constructed from durable steel. This material is chosen to withstand the demanding conditions, including heat and pressure, found within the engine's cylinder head area.

What does the 1.550 inch ID refer to?

The 1.550 inch ID (inner diameter) refers to the size of the opening in the spring seat. This measurement is important for ensuring it correctly mates with the specific valve springs you are using in your engine build.

About this part

Product Details

When you're rebuilding the top end of your engine, getting the valve train geometry just right is critical for performance and longevity. These valve spring seats from Manley Performance are designed to sit between the valve spring and the cylinder head, ensuring proper alignment and support for the spring. They are a well-made component that helps maintain the intended installed height of your valve springs, which is crucial for achieving the correct spring pressure and preventing valve float at higher RPMs.

Manley Performance is known for making solid internal engine components, and these spring seats are no exception. They are made from durable steel to withstand the heat and pressure found in the combustion chamber area. The 1.550 inch inner diameter is a common size, but it's always best to double-check your specific valve spring and cylinder head requirements to ensure a perfect match. Proper installation of these seats helps ensure your valve springs are seated correctly, contributing to a more reliable and consistent engine operation.
