I don't know the part number sorry. Stu from Murchisons sorted all that out for me. Half of the order has come across in container, and the other half is on it's way (I hope). It's silly that the oversea distributor split up an order like that. The bit I don't have is the e-locker and it's master install kit. I do have the the rear detroit tru-trac and new gearings though. It all has to go on at the same time so it's sadly gathering dust in a box right now

Flashy I was more concerned with the metallurgy, when I looked at and eaton I wasn't all that impressed with the machining and that automatically question the rest. I questioned a few guys in the states that had fitted them ( nephew and two of his mates) and decided to go with the ARB based on that.

All the guys I wheel with hate their ARB air leakers, I mean lockers. So much hassle and the compressor cycling every 10 seconds spoils the enjoyment. The others with e-lockers haven't had any issues I'm aware of.

I don't have the answer but if memory serves me correctly on the petrol models the factory fitted ratio is written on a round metal disc fastened to the transfer case. It's worth a look.

So any though on backspaceing for this size?

I had heard 4.25"-4.5" to get the 31.6" in (with grinding and trimming).

Have to educate myself tonight on this so any advice will be appreicated.

The AEV Procal type units don't work on our model so I haven't read of anyone being able to do it outside of the dealer scanners.

... happy to be educated differently if anyone knows better

Maybe Hypertech will do the job. I took a punt & purchased one for my grand & even though the web site had no listing for a CRD & it worked.
Model number Hypertech Speedometer Calibrators 752501, the same one listed on their site for the Liberty.

I would lone it to you guys but unfortunately it locks to your VIN
