GearMotive racing dogbox transmission products

GearMotive racing dogbox transmission products have been manufactured since 2015. Today BMW ZF transmission has been a famous product in many racing classes.

GearMotive products are innovative by it’s design. Many of the products are protected by patented innovation, which allows building a stronger dogbox gearset to a certain limited housing area than normally.


BMW ZF S5D dogbox gearset fits to M3, 325 and several other car models. The gearset has a handful of special features built-in. Shifter mechanisms are completely rebuilt, to make them as robust and rigid as possible. Clutch shaft is stronger than original and can be built for other splines as well. Gearset can be fitted any many car models with aftermarket adapters or by bell housing modifications.


For high power vehicles (over 500hp), we offer heavy-duty HD model counter and input shafts. The HD model gearset has been tested up to 1100hp/1100Nm in drag and drift racing. Check our reference page and videos how customers use the gearbox.

Subaru 2WD 5-speed dogbox transmission model for rear-engine cars. This transmission is an awesome choice for cars running with “old” VW beetle transmissions. Subaru Impreza / WRX 4WD transmission is a modern and strong basis to build dogbox transmission for 2WD rear engine use.

By closely going through the images, you may notice we have been able to increase gear widths 30% in comparison to original gear widths. This has been possible only by removing reverse gear between 1-2 gears in input shaft and moving it to different location. Input shaft is made of two pieces, allowing the use of different material for clutch shaft. Dog gears for 3. and 4. gears have been located to output shaft to improve shifting and reduce dog wear.

To switch Subaru transmission from front to back of the car, we are using special produced reversed ring and pinion set to turn transmission rotation direction.

Transmission can be fitted for different engines using adapter plates and custom flywheel options. Original clutch bearing has been upgraded to concentric slave cylinder usually.
