UH1-105 is a direct replacement to the stock hub that comes with all three models of the Simucube 2 family of direct drive base systems and also for VRS/Mige servos with the addition of the optional drivelock accesory.
It adds 105mm extra length to the stock hub and with smaller diameter is the perfect add-on in order to extend the motor shaft and give enough room and clearense for you center monitor in order to be as low as possible and to bring it closer to the servo axle.
Total lenght 155mm from the front face of the servo.
At the same time it is compatible both with the stock Simucube 2 quick release and also with any 70 PCD quick release on the market,
Both the stock SC2 QR and the 70 PCD holes are threaded M5 so no need for ugly nuts.
The UH1-105 is also compatible with out ProXT modular extensions for those that need more than 105mm extra length.
See this great video from Greg at GTGreg on how to install the UH1-105.

If you are having problems unlocking the drive lock that holds the shaft use one of the 4 M6 bolts in one of the 2 threaded holes circled in red in the picture below, once it bottoms out half an extra turn clockwise will unlock it. We suggest to leave a 5mm gap from the servo frame when installing the UH1 to avoid rubbing.

STH-105
I recently upgraded my sim racing rig with the Simcore extension, and it's been a game changer. The extension has allowed me to optimize my driving position for ergonomics, ensuring I don't have to adjust my pedal setup. This new configuration has significantly reduced the strain on my shoulder, which is particularly helpful given my history of a rotator cuff injury. Not only is it functionally superb, but the extension also has an aesthetically pleasing blue finish that enhances the look of my setup. It's a perfect blend of style and comfort for any serious sim racer.
