Supertech Performance Valve Thickness Nissan

Supertech Performance Nissan valve adjuster shims, also called valve lash shims or valve thickness shims, are precision-made replacements for the factory shims in Nissan shim-and-bucket valvetrains. They let you set accurate valve lash after cam swaps, valve jobs or other valvetrain upgrades.

Key Features:

• Direct replacement for the factory valve adjustment shims in supported Nissan engines
• Made from hardened material and ground to a precise thickness for accurate, repeatable lash settings
• Offered in fine thickness increments, so you can match the clearance each valve needs
• Useful when installing new valves, springs or camshafts, where correct lash is critical to valvetrain life and performance
• Sold by individual thickness, so you buy only the sizes you need

To choose the right shim, measure the clearance at each valve and pick the thickness that brings it into spec. Select the thickness option you need from the available variants.
