Mini gearboxes are a great way to upgrade when you don’t have a lot of space or don’t want to add a ton of additional weight to your car, truck or tractor. If you’re looking for a reliable mini gearbox, look no further than the twin counter shaft mini with reverser from SCS Gearbox. While this gearbox isn’t designed with the same lightweight reverser as its lighter counterpart, the fact that it’s small still helps cut weight.
