  • Pro X Valve Shim

    Pro X Valve Shim

    Owen in WV

    No more shim kits for me

    This is SO important ! When you buy these individual shims, you can get the "in between" sizes to get your clearances exactly where you want. Shim kits only have the full sizes, and the adjustments are too big. No more kits for me. I will buy the individual shims I want rather than sit with dozens of shims I will never use......and many times still don't have the half-sizes I need.
