Shimano XTR RD-M9120 Stroke Adjusting Screws & Plate

No, this specific hardware kit is engineered exclusively for the Shimano XTR RD-M9120 rear derailleur. It is not cross-compatible with other XTR series derailleurs due to specific threading and plate dimensions.

You will only need a standard Phillips or flat-head screwdriver, depending on your specific derailleur's screw head type. No proprietary tools are required for this installation.

These screws are often replaced if the heads become stripped from frequent adjustments, if the threads have seized due to corrosion, or if they have been lost during trailside maintenance. Replacing them restores your ability to accurately set the high and low limit stops for precise shifting.

Yes, this kit includes the necessary hardware to ensure the screws maintain tension and stay in place once adjusted. It is a complete set for restoring the derailleur's limit adjustment functionality.

Replacing the screws will only fix shifting issues if the problem is caused by the inability to properly set the limit stops. If your derailleur hanger is bent or your cable tension is incorrect, replacing this hardware will not resolve those specific mechanical problems.
