Maximize traction and performance with the Quaife ATB helical limited slip differential for the Focus ST / MMT6 gearbox. A direct replacement for the standard front 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
