Blackline Ford Sierra 7" Caterham Limited Slip Differential.

Unlike a conventional plate-style limited slip differential, the Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the ATB differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.

The ATB diff has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

We also offer a fitting service for the Limited Slip Differential. If you supply us your "open" differential we can fit this to your diff and will return this back to you. Please note, there will be a lead time for this.

If you do not have a differential, please contact us as we have several on the shelf in various ratios waiting to be converted

Please Note: On all Sierra differentials in order to fit the ATB, you will need to remove some of the differential casing in order to fit the LSD.  If you are attempting to fit this differential to a Labro (bolt in shaft) Ford Sierra differential, you will need the Quaife labro stub axles which are equal lengths.  You will not be able to use this LSD in a labro differential with the standard sub axels from Ford.
