Shimano Ultegra RD-R8000 Stroke Adjusting Screws & Plate

This specific kit, model Y3E998060, is engineered specifically for the Shimano Ultegra RD-R8000 rear derailleur. While some Shimano hardware is interchangeable, we recommend sticking to this specific part number to ensure the thread pitch and plate dimensions match your derailleur exactly.

You will only need a standard Phillips head or flathead screwdriver, depending on the specific screw head, to install these components. It is a straightforward swap that does not require removing the derailleur from the bike frame.

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 a crash or maintenance. Replacing them restores your ability to properly set the high and low limit screws, which is critical for preventing chain drops.

This kit includes the screws and the plate assembly as specified by the manufacturer. It does not typically include the small tension springs, so be careful not to lose those when removing the old hardware from your derailleur.

If your shifting issues are caused by the derailleur being unable to hold its limit settings, then yes, this will help. However, if your shifting is sluggish or imprecise, you should first check your cable tension, housing condition, and derailleur hanger alignment before assuming the adjustment screws are the culprit.
