Quaife Differential powers both drive wheels under nearlyall conditions, instead of just one. With an ordinary opendifferential, standard on most cars, a lot of precious power iswasted during wheelspin under acceleration. This happens becausethe open differential shifts power to the wheel with less grip(along the path of least resistance). The Quaife, however, doesjust the opposite. It senses which wheel has the better grip, andbiases the power to that wheel. It does this smoothly andconstantly, and without ever completely removing power from theother wheel.In drag-race style, straight-line acceleration runs, thisresults in a close to ideal 50/50 power split to both drive wheels,resulting in essentially twice the grip of an ordinary differential(they dont call open diffs peglegs for nothing).In cornering, while accelerating out of a turn, the Quaifebiases power to the outside wheel, reducing inside-wheel spin. Thisallows the driver to begin accelerating earlier, exiting the cornerat a higher speed.The Quaife also controls loss of traction when the front wheelsare on slippery surfaces such as ice and snow or mud, providing theappropriate biased traction needed to overcome these adverseconditions. The Quaife Differential provides constant andinfinitely variable drive. Power is transferred automaticallywithout the use of normal friction pads or plates seen in otherlimited-slip designs.The Quaifes unique design offers maximum traction, improveshandling 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 Quaifeis gear operated, it has no plates or clutches that can wear outand need costly replacement.The Quaife is great for street driving or racing. Racers donthave to put up with locking mechanisms or spools that createdunwanted understeer under power, or in the case of front-drivecars, even tear the steering wheel out of their hands

Differential powers both drive wheels under nearlyall conditions, instead of just one. With an ordinary opendifferential, standard on most cars, a lot of precious power iswasted during wheelspin under acceleration. This happens becausethe open differential shifts power to the wheel with less grip(along the path of least resistance). The Quaife, however, doesjust the opposite. It senses which wheel has the better grip, andbiases the power to that wheel. It does this smoothly andconstantly, and without ever completely removing power from theother wheel.In drag-race style, straight-line acceleration runs, thisresults in a close to ideal 50/50 power split to both drive wheels,resulting in essentially twice the grip of an ordinary differential(they dont call open diffs peglegs for nothing).In cornering, while accelerating out of a turn, the Quaifebiases power to the outside wheel, reducing inside-wheel spin. Thisallows the driver to begin accelerating earlier, exiting the cornerat a higher speed.The Quaife also controls loss of traction when the front wheelsare on slippery surfaces such as ice and snow or mud, providing theappropriate biased traction needed to overcome these adverseconditions. The Quaife Differential provides constant andinfinitely variable drive. Power is transferred automaticallywithout the use of normal friction pads or plates seen in otherlimited-slip designs.The Quaifes unique design offers maximum traction, improveshandling 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 Quaifeis gear operated, it has no plates or clutches that can wear outand need costly replacement.The Quaife is great for street driving or racing.
