Supertech 12.15mm Cam Follower Shim 2.10mm Thick

This product is a single Supertech 12.15mm cam follower shim, measuring 2.10mm thick. It's a small but important piece for adjusting valve lash in certain engine builds. When you're rebuilding the top end or fine-tuning your engine's valve train, these shims are used to set the precise clearance between the camshaft and the valve bucket or rocker arm.

Getting the valve lash set correctly is crucial for engine performance and longevity. Too much clearance can lead to noisy operation and poor performance, while too little can cause valves to stay open slightly, leading to burnt valves and reduced compression. This shim is made to the exact specifications needed for accurate adjustments.
