Performance Gearboxes

If you love high horsepower Bailey Automatics are the place to go for a gearbox upgrade to a high performance gearbox.
Factory gearboxes are only designed to handle street driving. If you’re planning on using a factory gearbox for track racing, drag racing or drifting it will likely fail on you. You’ll need a performance gearbox!
If you’re thinking about an upgrade, give Stew a call to discuss what you need. He’ll need to know a few things. For a start…what type of car the gearbox is for? And what horsepower the car has as this will impact on how far we can go with building what you need. In addition, what type of driving are you doing and what will you be using the car for most of the time? If you’re using the car for 80% street and 20% drag then we’ll set the gearbox up accordingly; if the performance gearbox is purely for drag racing then we’ll set it up differently again.

Drive it Hard

The harder you plan on using your car, that is, the more performance and more horsepower you need, will determine the quality of gearbox parts required. If the vehicle is going to be driven hard then tough, reliable and virtually break-proof parts will be used for your performance gearbox.
