COMP Cams Spring Shims Eb .030 X 1.250in

When you're rebuilding the top end of your engine, getting the valve springs set up just right is crucial for proper valve train function. These valve spring shims from COMP Cams are designed to help you achieve that perfect setup. They're made from high-quality shim stock that's been heat-treated, so they can handle the demands of aggressive camshaft profiles without deforming.

Using these shims is a straightforward way to ensure all your valve springs have the same installed height. This consistency is important because it helps maintain the correct spring pressure across all cylinders, which leads to more reliable engine performance. They measure .030 inches thick with a 1.250-inch outer diameter, fitting common valve spring setups.
