These COMP Cams valve spring shims are made from high-quality shim stock that's been heat-treated to handle aggressive camshaft lobe profiles. When you're rebuilding an engine or swapping cams, ensuring your valve springs are installed at the correct and equal height across all cylinders is crucial for consistent performance and valve train stability. These shims are a straightforward way to achieve that precise installed height.

Each shim measures .015 inches thick and has an outside diameter of 1.640 inches, with an inside diameter of .635 inches. The heat-treated material means they can stand up to the demands of radical camshafts without deforming, helping to maintain proper spring tension and valve control over time. They are a simple, effective solution for fine-tuning your valve spring setup.
