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.
