SRT Gearbox

I am working on a 6 speeds gearbox that would be controlled by an hydraulic clutch pedal !

You want to support this project ?


The best gearbox in the world:

  • 6-speed H-box + reverse gear
  • Sequential (we go from one to the other in 3 seconds)
  • Clutch mode (optional): if you don’t press the clutch pedal, the gearbox stays locked (only in H mode)
  • Multiple attachment points (from underneath and from the side)
  • Adjustable front-rear and left-right feeling
  • Adapter to mount a hand brake (P1)
  • Possibility to connect pedals to it
  • For about 140€.

All the documentation is available on the Discord

Development History:

I am currently printing the structure to hold all the parts together. I am also waiting for 4×100 metal shafts to replace the printed ones I installed.

v4 :

I've been passionate about cars since I was a kid! I learned the multiple variations of the Skyline R34 through the Gran Tursimo series, until I discovered GTR2 at the wheel of a keyboard. A few years later, I plunged back into Sim Racing with a G27 which made me enter the DIY world. Always looking for an immersion out of reach in reality, I develop projects that I take care to make accessible to any 3D printer owner!

  1. Hi,

    you are great engineer and there are posted some of the most amazing mods ever,

    But some pictures above are missing.

    I also do wonder about password protected content there. Is it temporary? Are you selling access to it?


    1. Hi ! Thanks for your message.
      There is a bug about the pictures… Feel free to inform me if they are missing, it just takes a couple of seconds to put them back.
      The actuators documentation is currently under construction, so I added a password to work on it. It almost ready and should release soon.
