About this part

Product Details

When you're rebuilding the top end of your engine, getting the installed height of your valve springs just right is crucial for proper valve train geometry and performance. This COMP Cams shim kit helps you achieve that precise setup. It contains shims designed to sit between the valve spring and the cylinder head, allowing you to make fine adjustments to the spring's seated height.

This kit includes a generous supply of shims in three common thicknesses: .015", .030", and .060". Each shim has a 1.437" outside diameter and a .645" inside diameter, suitable for many popular valve spring applications. The shim stock is well-built and heat-treated to handle the stresses from aggressive camshaft lobes, ensuring they hold up over time. Having these different thicknesses on hand makes it much easier to get all your valve springs sitting at the same installed height, which is key for consistent valve spring pressure and preventing issues like coil bind.
