Aluminium DIY Knobs & Adapters

Explore aluminium knobs and adapters for DIY sim racing controls. This collection includes TFS encoder knobs, joystick and joycoder caps, a button-box knob and shaft adapters for custom wheel or button-box builds.

Match the shaft and the available space

The AMR, GT, LMP and GTE encoder knobs are specified for 6 to 6.35 mm shafts. The joystick/joycoder knob uses a 2.5 mm shaft, while the dedicated adapter allows a suitable 6.35 mm knob to be fitted to a 3.2 mm shaft. Always confirm the exact reference rather than assuming all knobs share the same bore.

Check diameter, height, retaining screw and clearance around neighbouring controls. These are control components, not cockpit aluminium profiles or brackets. See DIY steering wheel parts for other assembly components.
