HEAVY DUTY X-PIN DIFFERENTIAL

The X-pin differential has been designed for a significant increase in strength over the standard unit. The X-pin copes with more power, and with the addition of the two extra planet gears comes a much smoother drive.

We highly recommend these for all performance applications, as the standard single-pin differential can fail quite quickly with any enthusiastic use.

The design includes two special steel molybdenum coated X-pins with four planet gears and two thrust washers for the outputs shafts. You can either re-use your original output shafts, or we can supply new ones.

For early Minis with Hardy Spicer output shafts, these components are quite hard to find in good used condition and are no longer made, so we suggest to use the later pot joint output shafts and a set of MED Hardy Spicer adapters.

If you're looking to increase traction off the line, the X-pin is still an open diff, so we would look instead towards the MED ATB differential for fast road and trackday usage, or the NXG limited-slip differential for full competition.
