Supertech Cam Follower Shim 8mm Dia 1.90mm Thick

This product is a single Supertech cam follower shim. It measures 8mm in diameter and is 1.90mm thick. Shims like these are essential for fine-tuning the valve lash in your engine, ensuring your valvetrain operates with the correct clearances.

Proper valve lash is critical for engine performance and longevity. Too much lash can lead to noisy operation and reduced power, while too little can cause valves to stay open slightly, leading to burnt valves and poor sealing. This shim allows mechanics to make precise adjustments to achieve the manufacturer's specified clearances.
