Pair of Tractor and Trailer REAL TRUCK air brake knobs with aluminum adapters inside to fit your ATS/ ETS button box. 


Change out your 3d printed truck air brake knobs with REAL TRUCK AIR BRAKE KNOBS for more of an authentic experience. 

• Thread is M5 which fits most ATS/ETS button boxes. You may want to check with the maker of your button box to confirm but I have tested most of the major brands and they screw on to the M5 smaller thread.

  *If you need just the aluminum adapters we sell those as well just check our other items. 
  
  
• Should fit ASP and ATS accessories semi truck simulator ATS Boxes as they use M5 thread for push pull trailer tractor knobs.
