COMP Cams Spring Shims Eb .030 X 1.500in

COMP Cams is well-known for performance valvetrain components, and these valve spring shims are no different. They're made from high-quality shim stock that's been heat-treated to stand up to aggressive camshaft lobe profiles. If you're rebuilding your top end or swapping cams, getting the installed height of your valve springs just right is crucial for consistent performance and valve control. These shims are a straightforward way to achieve that consistent installed height across all your springs.

Each shim measures .030 inches thick, with a 1.500-inch outer diameter and a .645-inch inner diameter. This specific sizing is important for ensuring they fit correctly with your valve springs and retainers. By using these shims, you can make sure each valve spring is seated at the same height, which helps prevent issues like spring bind or inconsistent valve spring pressure. This attention to detail is key for a well-performing engine.
