ARB do a front and rear air locker for the D3/D4
IIRC ARB have withdrawn the D4 rear locker.
No ARB rear locker for D4. Everytime i ask them, they say no demand and that i'm the first person to ask. I've asked a few times over the years from a couple of different stores so their counting is not quite right.
Mine doesn't have a rear locker, i wish it did but i'm probably in the minority of people who push these things to the point that it would be frequently beneficial. If one became available (preferably retro-fit LR) i would be all over it.
A retrofit of the OEM e-diff can be done and has been done. But it would take time, cash and skill.

They link to us, so I see no issue linking to them...
I would also ask if you were stuck if you are sure you were in rock crawl mode. It is amazing how much difference it can make. I was all ready to winch myself out of a tough rocky steep incline one day after trying everything I could think of short of that when I decided to have one last go and realized I was still in grass, gravel snow mode. Put it in rock crawl and it just walked out no sweat at all.
Unless you frequently push the car to the extremes I would go tyres and pressures first before the complexity of trying to retrofit the e diff. Next would be an ARB locker.
If I was buying new now I would specify the e-diff, just because I could, not because I have experienced a real need for it, I have gone some pretty amazing places without one.
If I was buying new, I'd definitely order a locker as they are such a small addition to the total price.
However, there are many many D4's running around Australia that get very serious off road that do not have one.
Gordon from GOE told me he felt that in the later vehicles, the traction control had got that good there was less and less reason for an e-diff being a needed item.
As the others had mentioned, tire pressures and terrain response mode choice are likely to have a lot more to do with how far you will get on wet rock.
Mark..... Tire? You going all Yankee on us
What's with all the wheel lifting in the video?

D3s don't need all the wheels on the ground to progress..... they kind of do that naturally off road, it makes for good footage if they have a few wheels in the air though, and there may have been some playing up for the camera involved.Quote:
