Quaife ATB Differential, Fiesta ST 2014-2019 with IB6 transaxle *FREE SHIPPING*

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. Quaife PN QDF57Z 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.
