The X-pin concept grew out of development work carried out by David Hirons in the mid Eighties to resolve the problem of persistent diff bevel gear and carrier failure on rear wheel drive Ford Escorts and Lotus Cortinas. The torque capacity of the diff could be increased by adding two extra bevel gears. The cross axle torque transfer was unaffected. Modern material technology was introduced to overcome lubrication problems with the pin and bevels.

25 years ago in 1993 the decision was made to resurrect the manufacture of the four star diff and apply the latest technology to the Mini. The new product was released and protected under UK and European design laws by copyright licence: Doc c1993.

It is now manufactured for Mini Spares Centre under licence. Over 5000 have been sold to date with an unblemished success rate!
