Can be installed on M12 shift knobs and AT shafts within 14mm. 【Set Screw Fixing Type】 Can also be fixed to oval AT shafts. 【Push Type】 The lock release, which was previously done by pressing a button for gear changes in automatic cars, is now done by pushing the shift knob down. Easy to use in passenger cars, kei cars, and kei trucks.

Please be sure to check the size before purchasing. We do not confirm compatibility for each vehicle model. ※ The operation will be different from AT cars, so driving while you are not used to it is very dangerous. Please get used to the operation before driving.
