Maximize traction and performance with the Quaife ATB helical limited slip differential for the Focus ST / MMT6 gearbox. A direct replacement for the standard Ford open differential, the Quaife ATB differential transforms your car's performance and improves cornering. Unlike a conventional plate-style limited slip differential, the Quaife differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation and never locks harshly with a set pre-load of wheel slip across the driven axle. Instead, the Quaife differential automatically biases the torque away from the spinning wheel, across the axle to a constantly varying degree.

Benefits over a standard open differential:

  • Maximize traction
  • Minimize wheel spin
  • Reduced torque steer and snatching in front wheel drive cars
  • Maintenance-free design which retains the standard oil lubrication
  • Quaife differentials are proven in circuit and drag racing, rallying and road use.
  • All Quaife differentials are produced from Corus steel billets, and are CAD-designed and CNC machined before being inspected to ISO 9001 standards.
  • Quaife Automatic Torque Biasing Differential - Track Tested and Proven.

Fast Shipping and the best price February 26, 2015
Reviewer: Robert O. Redman from Waynesburg, PA United States  
This was one of the smoothest transactions I have ever made. Had the differential in 4 days. Then on top of that it is the best price on the net and free shipping. Definitely will buy from again. Thanks Rob
