Supertech Cam Follower Shim 8mm Dia 2.45mm Thick

When you're rebuilding the top end of your engine, getting the valve lash set just right is critical for performance and longevity. These 8mm diameter cam follower shims from Supertech, specifically 2.45mm thick, are designed to help you achieve that precise adjustment. They are a common need when replacing camshafts, valves, or valve springs, as these components can alter the valve train geometry.

Supertech makes these shims from hardened steel, which is important because they sit between the camshaft lobe and the valve bucket or rocker arm, taking direct impact with every rotation. The 8mm diameter ensures it fits correctly within the valve train assembly, and the 2.45mm thickness is a specific size needed for certain applications to set your valve clearance within the manufacturer's specifications. Having the correct shim size means your valves will open and close at the right times, ensuring efficient combustion and preventing potential damage from incorrect lash.
