Supertech Nissan RB26 Factory Shim Replacement 12.15mm Diameter 3.55mm Thick

Supertech is known for making well-built internal engine components, and these valve shims for the Nissan RB26 are no exception. If you're rebuilding the top end of your RB26 or just doing a valve adjustment, having the right shims is crucial for setting your valve lash correctly. These shims are designed to replace the factory ones, ensuring proper fit and function within your engine's valvetrain.

Each shim measures 12.15mm in diameter and is 3.55mm thick, matching the factory specifications. Using precise shims like these helps maintain the correct clearance between your camshaft lobes and the valve buckets, which is essential for optimal engine performance and longevity. Getting this clearance right ensures your valves open and close at the correct times, preventing potential damage and keeping your engine running smoothly.
