About this part

Product Details

When you're rebuilding the top end of your engine, getting the valve springs installed at the correct and equal height is crucial for consistent performance. These valve spring shims from COMP Cams are designed to help you achieve that precise setup.

Each shim measures .030 inches thick with a 1.640-inch outside diameter and a .635-inch inside diameter. They're made from well-built shim stock that's been heat-treated. This treatment helps them stand up to the demands of aggressive camshaft lobes, ensuring they maintain their integrity and function over time. Using these shims helps equalize the installed height of all your valve springs, which is important for proper valve train operation and preventing potential issues down the road.
