What is the purpose of a valve spring seat?

A valve spring seat is a small component that sits at the base of the valve spring. Its main job is to provide a stable and correctly sized platform for the valve spring to rest on, ensuring it functions as intended within the engine's valve train.

What does 'SPRING CUP-ID 1.311' mean?

This measurement refers to the inside diameter of the cup where the valve spring sits. A 1.311-inch ID is specific to certain valve spring designs and engine applications, like the LT4 exhaust valves this part is intended for.

Does this part come with other valve train components?

This listing is for the Manley Valve Spring Seat (part number 42161-8) only. Other valve train components, such as the valve springs themselves, retainers, or seals, are typically sold separately.
