Supertech Nissan RB26 Factory Shim Replacement 12.15mm Diameter 3.10mm Thickness

Supertech is known for making well-built internal engine components, and this valve shim is no exception. If you're working on a Nissan RB26 engine and need to adjust your valve lash, this shim is designed to be a direct replacement for the factory part. It measures 12.15mm in diameter and has a thickness of 3.10mm, ensuring it fits precisely where you need it.

Getting the valve lash set correctly is important for engine performance and longevity. Too tight, and you risk valve damage; too loose, and you'll have noise and potential misfires. Using a shim of the correct size, like this one from Supertech, helps you achieve the proper clearance for your RB26's valvetrain.
