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.

The whole purchase experience and fitment of my atb was faultless, great price on Black Friday deal and fitment arranged and completed at my convenience. Also had a quick shift installed at the same time, my only regret is I didn’t do it sooner, stage 2 car now maximising it’s full potential. I highly recommend Mountune for any of your needs and will not hesitate in returning for any future work.
It's a real pleasure visiting mountune hq yesterday and you really can see why people come from far and wide to experience a great service from Ryan and the team along with some outstanding products. I have now had this new dif added to my mr230 to improve the cornering even further to what is already a remarkable little car. On the drive home l could tell immediately what they had done had really worked. Thanks alot mountune and no doubt, see you again soon,
Really impressed, makes a big difference going round corners and getting on the power much earlier. The best mod I’ve had done so far especially if you’re running more power. Everyone down at mountune HQ were very friendly and helpful while I was waiting for the installation.
