Available exclusively from mountune, the Quaife ATB helical LSD differential for mk7 Fiesta ST fits the B6 gearbox. A direct replacement for the standard Ford open differential, the Quaife differential transforms your car's performance.
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:
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.
Fitted price includes the following:
