Supertech 8mm Shim 3.50mm Thick

This 3.50mm thick shim is made from hardened steel, a solid choice for ensuring your engine's valve lash is set precisely. When you're rebuilding an engine or performing routine maintenance that requires valve adjustment, having the right shim size is critical for proper engine operation and longevity. This particular shim is designed to fit 8mm valve stems, a common size in many performance and import applications.

Getting the valve clearance just right helps your engine breathe efficiently and prevents potential damage from too tight or too loose clearances. Using a well-made shim like this one from Supertech means you're getting a part that's built to withstand the heat and stress inside the combustion chamber. It's a small part, but it plays a big role in how your engine performs and sounds.
