The Supertech factory-style shim for Nissan RB26 engines is a direct replacement valve shim sized 12.15mm in diameter with 3.20mm thickness. It provides OEM-dimension replacement where shim-over-bucket valve trains require precise thickness control during valve adjustment or rebuilds. Keep a set on hand for service and maintenance to restore correct valve clearance without modifying the original valvetrain design.
