The Quaife ATB Differential
In recent years, there has been a large increase in the use of motorcycle engines in cars for both road and racing. The unique design of the Quaife ATB Differential soon found favor with constructors as it was able to withstand the harsh environment of an open, chain-driven transmission. We now offer a differential, based upon a Ford Fiesta diff application, that is sealed to allow it to run open-air style.
- Sealed unit - only requires greasing
- Based on Ford Fiesta
- Uses stock Ford Fiesta outputs

In addition to the differentials, we have designed an epicyclic type reversing box used to overcome the problem of not having a reverse gear when using a motorcycle gearbox in a car.
It is a straight-through type in forward mode and therfore absorbs less power than a conventional design.
Available as an in-line unit for front engined cars, it is extremely durable and compact and can be operated by cable or by other remote devices.
- Compact, heavy duty unit - only 7.635" OAL
- Straight through design - low power loss
- Aluminum billet cases
- Uses Ford English flanges
