JEGS Valve Spring Shim Kits

Product images may differ from actual product appearance.

The smallest details can yield the biggest results. JEGS Valve Spring Shims are not the ordinary piece of heat treated steel most others call a valve spring shim. Our .030" and .060" thick valve spring shims are case hardened and feature serrations that help dissipate heat. Our .015" shims are made from blue tempered spring steel. These valve spring shims can easily withstand the abuse of a high-performance engine or a daily driver. Each kit includes 16pcs each of .015", .030", and .060" valve spring shims. Made in USA.
