COMP Cams Spring Seats .045 X .520 X .8

These COMP Cams spring seats measure .045 inches thick, with an outer diameter of .520 inches and an inner diameter of .800 inches. They are designed to sit between the valve spring and the cylinder head, providing a stable base for the spring and helping to ensure consistent valve train geometry. This is a well-built component that's important for proper valve spring function in many engine builds.

When you're rebuilding an engine, the details matter. These spring seats are made to precise dimensions, ensuring they fit correctly and perform as expected. They help prevent the spring from damaging the cylinder head surface and provide a solid foundation for the spring's load. Using the right spring seats is a small but crucial step in getting your valve train set up correctly.
