Product Details

This package includes 16 Manley valve spring seats, part number 42126-16. These are designed to sit at the base of your valve spring, providing a solid foundation and proper alignment within the cylinder head. They are made from durable steel to handle the stresses of engine operation.

Having a well-built seat helps maintain consistent spring pressure and prevents damage to the cylinder head surface over time.
