The QUAIFE Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster. How? By getting the power to the ground! The QUAIFE Differential powers both drive wheels under nearly all conditions, instead of just one.

An ordinary open differential is the standard on most cars. A lot of precious power is wasted during wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip, along the path of least resistance.

However, The QUAIFE does just the opposite. It senses which wheel has better grip and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel. In cornering, while accelerating out of a turn, the QUAIFE biases greater power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The QUAIFE'S unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street. The QUAIFE is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement. The QUAIFE is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the cars limits. The QUAIFE has been proven in everything from SCCA Rally to Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.
