Supertech 8mm Shim 3.20mm Thick

This 3.20mm thick shim is made from hardened steel, a strong material that holds up well under the constant pressure and heat found in an engine's valvetrain. It's designed to fit 8mm valve stems, a common size in many performance and stock applications. When you're adjusting your valve lash or rebuilding your cylinder head, having the right shim thickness is crucial for setting your valve clearances accurately. This ensures your engine runs smoothly and efficiently, preventing potential damage from incorrect valve timing.

Supertech is known for making well-built valvetrain components, and these shims are no exception. They are manufactured to precise tolerances, meaning you get a consistent thickness that makes setting your valve lash a straightforward process. Getting the valve clearance just right is important for both performance and longevity, as it allows the valves to seal properly and prevents them from hitting the piston at top dead center.
