Thread: Ashcroft Locking Diffs

I organised a fully built up Ashcroft air locker diff centre for a friend's RRC, complete with pegging, and the owner couldn't be happier. The diff pegging is like an insurance policy, rarely needed but handy if you ever have to give it a bit of curry in a difficult spot.

Does any one have feedback positive or not about the performance and reliability?
One last question has anyone bothered with the Ashcroft pegging kits to strengthen the diff housing?
My disco is a td5 auto mainly used for touring and fairly easy off road not extreme completion.
Thanks in advance.

For the use you mention, I would have thought the ashcroft ATBs would have been quite adequate. I have a pair of similar trutracs on both cars, and could not be happier. Fit and forget!!

IMO the Ashcroft locker is one of the best designed/engineered lockers for a Rover diff you can get.
As beeutey said, pegging is insurance, but if you are just running standard sized tyres probably not needed.

If you were ruining a Maxi Drive low low, 33"+ tyres and a big chip, big IC, etc then yep, definitely worth doing.

Have you considered jack McNamara 6 gear centers and Ashcroft axles, I run this set up on my td5 auto cheaper than lockers, but tough enough for what you describe.

Hi to the forum
Thanks for the reply's gives me some ideas.

Regards

I run the ATB front and rear. With the traction control they are the bees knees. Couldn't be happier.

Whichever you decide to go with you will not be disappointed with the quality. Remember if you decide to go ATB and pegged then the outside circumference of the ATB needs to be machined, i'm not sure if you are required to do this with the locker. Best ask Ashcroft to be sure.

Do Ashcroft arrange the machining prior to delivery? I'm surprised that they haven't modified the case sizing to suit instead.

I have Ashcroft Air locker pegged and yes the carrier (centre) needs to be machined to clear the pegging see attached pic`s.
Who ever set`s th diff up should be able to do this mod in a lathe ,This is what Dave Ashcroft does so is done with his approval.
