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, flat surface for the valve spring to rest on, ensuring it applies consistent pressure.

What does the 'LT4inT' designation mean?

This designation typically indicates compatibility with specific engine configurations, such as the LT4 engine, and suggests an 'inward' or specific orientation for the seat within the valve train assembly.

What material is this valve spring seat made from?

While the specific material isn't detailed, Manley Performance is known for using well-built materials suitable for the high-stress environment of an engine's valve train.
