Mountune Quaife ATB Differential Fiesta ST

Maximize traction and performance with the Quaife ATB helical limited slip differential for the Fiesta ST / B6 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.
