Quaife ATB Differential, Fiesta ST 2014-2019

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. All Quaife differentials are produced from Corus steel billets, and are CAD-designed and CNC machined before being inspected to ISO 9001 standards .

5 of 5 Quaife ATB LSD Install - Fiesta ST May 30, 2020
Reviewer: Marc from PRINCE GEORGE, BC Canada  
This upgrade while the most expensive I've done to this car is probably the most positive in terms of results, the traction out of corners is rather impressive really changes the dynamics of the car. I have the full MR230 hardware with mountune custom tune, the car now feels more confidant in all corners from entry to exit. I bought the Ford Performance differential kit from mountune, you also need Ford differential shims, transmission case bolts. I bought the input/output shaft bearing kit with comes with input/output case shaft bolts (6), (2) end bolts, input/output shaft bearings and input shaft seal. All of these bolts I talked about above the Ford service manual recommends replacing them. Would recommend buying this input/output bearing kit from Ford AV6Z-7L149-A. While having the transmission apart I had a X-Clutch w/ chromoly flywheel w/ improved inertia installed. I went with Motul DCTF fluid but went back Ford DCTF, too notchy. The smile on face is even bigger now :)

5 of 5 Superior Modification! July 24, 2017
Reviewer: Stanley Willis from Pittsburgh, PA United States  
The Quaife ATB Diff is, without a doubt, one of the best modifications I've made to my 2014 Fiesta ST.  Now, the power of my MR230+ kit is going to the road instead of making the front wheels spin under hard acceleration in my first three gears.   Torque steer has almost completely vanished and the mid-range acceleration is absolutely ferocious.  I can't wait till our second autocross season hits this fall.

Reviewer: Norman Crawford from Frisco, CO United States  
Where are the instructions to install the
Quaife differential.
The Quaife looks like a great product but how
To install it remains to be seen.

I guess I am on my own?
