High guys just wondering how strong the Jeep stuff is compared to the Rangie's and Discoveries so I have a better idea of the tyre size I should go with.
I pretty much know the limits of the Rangie stuff.
I am thinking of 31" claws to go on my ZJ however maybe I can get away with something in a 32". I don't want to have to baby it and fix diff/axles all the time.
Cheers.

do a search on a dana 30 front and dana 44 rear
not biggest baddest comp style axles but pretty reasonable up to 35's
for 31/32 no problem the only thing to watch jeeps are pretty under geared from factory and you take a performance hit going up in tyre size to do it correctly after 31's you should plan a ratio change others dont mind the performance drop so each to their own

i could be wrong, but thought the ZJs have a D35 rear diff. If thats the case, than 32s is the biggest recomended size esp if you lock it. The D44 would hold out locked with 35s and there are heaps of axle upgrades, lockers and artios avaliable (for all Dana diffs in Jeeps).

Correct, ZJ has a 35 rear...

A very small number got Alloy D44's......not really that much better than the D35....
But chances are it has a D35 POS....

Ok Wooders, what's stronger Rangie diffs and axles or Jeep diffs and axles. I believe the Rangie is a bit bigger. Does that make it stronger?
I do like the high diff clearence ( I still have bad memories from the GQ days of getting stuck on diffs),
Going by what I have read a bit of guard chopping and a 3" lift should fit 32's but I am still a bit concerned I am going to break stuff.
I have read that trussing the diff/ axles help a lot to save them.
Does anyone here have experience with the A frame conversion that they have for the ZJ. It is a 4" lift?

ive looked into trussing and doing the super 35 kit, its very exxy and ended up getting a Dana 44 from a TJ (that i have to fab, lock and re-gear -in progress) which will be still stronger and cheaper than a super 35.
