ASHCROFT DIFF PEGGING

A method of strengthening the Rover differential.

If you are heavily off-roading your Rover, one of the first mods you will need is to change the diff center for a stronger one- be it either Detroit locker, ARB or other- once you have the diff center up rated you may still experience a failure of the crown wheel and pinion gears.

The reason for the ring and pinion failing is because when the diff is shock loaded, the pinion will push the crown wheel away as the diff center flexes, once the pinion teeth start to ride up the crown wheel teeth this can allow the pinion to spin and take some teeth off either gear.

Ashcroft "Peg" the diff to hold the gears in constant mesh by putting a thrust pad behind the crown wheel, opposite the pinion, this means the pinion cannot push the crown wheel away.
Lucky8 can provide this service on your current diff set up or we can build you one from scratch.
