⭕ Purchasing & Installation Tips

◉ Before you buy, remove the factory knob and measure the outer diameter (OD) of the two internal bearings (or plastic sleeves):

◑ Two × 7 mm OD → choose the D-Cup package.

◑ Two × 9 mm OD → choose the NS-Cup package.

◉ You typically do not need extra bearings. Reuse the bearings/sleeves from your original knob and follow the included diagram. Ensure all parts are clean, aligned, and spin smoothly after installation.
