As a direct replacement for the standard, factory ‘open’ differential, Quaife’s ATB unit can transform the performance of your car. Unlike a conventional plate-style limited slip unit, these units rely on gears, rather than clutch plates for its operation.
That means it’s much smoother in operation, because unlike a conventional plate-style LSD, it never locks harshly with a set pre-load of wheel slip across the driven axle.
Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree and never locks.
To the driver (especially of a front-wheel drive car), the results are significant performance improvements; superior, controllable traction without the harsh steering wheel snatch or torque steer that have long been associated with performance differentials.
These traction benefits can also be utilized in rear wheel drive vehicles, while Quaife ATB units offer significant traction advantages fitted to the front of four wheel drive cars.
These units require no special maintenance or rebuilds, are long lasting and retain the standard method of lubrication, making for an easy, pain-free upgrade.
