These adapter conversion screws are perfect if you have bought a shift knob or want to get a shift knob for your Japanese car with the wrong size direct thread.

1 x flanged calibre conversion screw by Jet InOue to fit thread 8x1.25 (gear stick side) and will convert to 12x1.25 (shift knob side).

Please do check your specific application to avoid any disappointment. This adapter screw will convert the 8x1.25 thread to a 12x1.25 thread which will then allow you to fit a JDM shift knob that is of a 12x1.25 thread without changing the height dramatically.

Fixing can be done with a 14mm wrench on this particular adapter.

Product description:

  • Material: Brass/Chrome Plated
  • Total Length 40mm/Screw Length: 20mm
  • Collar height: 2mm

We stock plenty of unique JDM shift knobs. Adapters are normally supplied with the majority but if not an adapter can be supplied free of charge with the purchase of any of our shift knobs. We can also source various sizes as per requirement so please do get in touch if you require a different size thread adapter and we can try and get one into stock for you.
