Supertech 8mm Shim 3.30mm Thick

This 3.30mm thick shim is made for 8mm valve stems. It's a critical piece for setting the correct valve lash in your engine. Getting the valve clearance just right is important for performance and engine longevity, ensuring the valves open and close at the precise moment they should.

Supertech uses solid materials to make these shims, so they hold up to the heat and pressure inside your engine. They are designed to fit precisely onto the valve stem, making installation straightforward when you're rebuilding your top end or performing routine valve adjustments. This specific shim size is often needed to dial in the perfect clearance after valve work or when using different camshafts.
