Quaife ATB Info & FAQ's
Quaife’s range of products includes the ATB helical gear limited slip differential, which is designed to improve the traction of any front, rear or four-wheel drive car. With outstanding reliability and performance, Quaife ATB’s are actively used in rally, racing, track day and fast road fitments.
What sort of gear oil should I use ?
When running a Quaife ATB helical gear limited slip Differential in a standard transaxle gearbox, we recommend that you use whatever your vehicle’s manufacturer recommends. The Quaife ATB Differential does not require any special lubricants. When running Quaife gearbox internals and a Quaife ATB differential – we recommend FuchsTitan SYN5 75W90. For a Quaife ATB differential, running in a rear axle – use a hypoid 90 or 75W90, as above.
What is the torque bias ratio of the Quaife ATB differential?
Quaife does not specify bias ratio details and generally, does not use the term. The Quaife ATB differential is an all helical gear design. The angle and tooth form of the helix used, the number of pinions used and many other factors (including the individual vehicle application in question) all contribute to how the differential behaves and biases drive torque across an axle. Each Quaife ATB differential application is designed to offer the best compromise between performance and durability, which is why it is regarded as the industry benchmark design.
What kind of horsepower can the Quaife ATB differential handle?
The Quaife differential is engineered to handle considerable amounts of power and high torque loadings. In almost any given transmission or rear axle, the Quaife ATB Differential will not be the limiting factor, this has been proven in front wheel drive drag racing where violent standing starts combine with high power outputs and sticky drag rubber If you have any questions regarding this, please feel free to contact us.
What sort of maintenance is required when using a Quaife ATB differential?
There is no additional maintenance required when using the Quaife ATB differential. It is a ‘fit and forget’ item without any internal plates, springs or washers to wear out.
Are there any special parts needed to install a Quaife ATB differential?
There are no special parts required to install a Quaife ATB differential, beyond what may normally be needed to install a stock unit. The basic parts needed will be: differential bearings, transmission or rear end gaskets and possibly some shims if required.
