What is the purpose of a valve spring seat?

A valve spring seat sits at the base of the valve spring, providing a stable platform. It ensures the spring is correctly positioned and helps maintain consistent pressure for proper valve operation.

What does the '1.580' measurement refer to?

The '1.580' refers to the inner diameter of the valve spring seat. This measurement is important for ensuring it mates correctly with the valve spring and the cylinder head surface.

Are these seats compatible with all valve springs?

These specific seats are part of Manley's 42369 valve spring set. While they are a common size, it's always best to verify the inner diameter against your specific valve spring requirements.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these valve spring seats are no exception. They are designed to sit at the base of your valve spring, providing a solid foundation and ensuring the spring is properly seated. This is a critical step when rebuilding or modifying your engine's cylinder head, as it helps maintain consistent spring pressure and valve control.

These spring seats have an inner diameter of 1.580 inches, which is a common size for many performance applications. They are sold in a set of 16, enough for a typical V8 engine. Using well-made spring seats like these helps ensure your valve train operates smoothly and reliably, especially under demanding conditions.
