Won't work for you. I mean you could probably modify it to work, but you'd have to modify A LOT.

The brakes you want are from a ford explorer. Anything solid axle with disc brakes.

Basically the same as the ZJ, but more common and a better finished product.

8.25.
But i appeares zj disc flanges bolt on dana 35 8.25 and 44.
I am not afraid of modding. Thought about welding brackets on and running chevy half ton or anything with 5x4.5 rotors

Just have seen no reason newer than 98 zj brakes cant work.
When did 5" lug pattern happen

Evan03,
You might also look at KJ Liberties. I believe those were all equipped with 8.25 rear ends with disc brakes.

Yep, the KJ brakes fit the 8.25" with no mods!

Pretty much all zj brakes will work as well as liberty brakes. I think liberty will be easier because you dont have to enlarge the centerhole as much.
99 was the start of the wj's and the 5x5 bolt pattern. You can use wj parts also but you will have to redrill your rotors. It might be possible to use zj rotors on the wj disc setup but i am not possitive.

ZJ rotors will not work with WJ calipers! There is absolutely nothing to modify with KJ backing plates.

Even with ZJ parts, the hole can be enlarged very easily. You SAND it......

Im gearing up to do the KJ swap. figured itd be the simplest. done have to grind anything. just longer mounting bolts, and D30 front wheel studs and your in business. Do have to mess with the hardlines a bit, but doesn't cost a lot.
