I have heard that you can put ZJ rear disc brakes on a XJ. Is this true? If so what years and what parts are needed? Will it work on all XJ's? Is there a write up on here already that explains how to do this upgrade?

Thanks

^^ lol

In short form, find a ZJ and take everything for the rear brakes.

Here is a quick link, http://www.madxj.com/MADXJ/technical...rDiscsOnXJ.htm

 

95-98 models.

 

im confused. the link to madxj says he's doing the swap on a 87 XJ with a D44 will the swap still work for the Crysler 8.25 axle??

 

Yes, it will still work. Just google 'zj rear disc swap' you will get a hundred write ups on the subject. Its easier then me tryin to explain it without pictures.

 

The swap to a D35 is a direct bolt on with no mods. To an 8.25 it is the same accept the center opening has to be enlarged slightly to accommodate the 8.25. If you do a search on this site and Google you will

 

I just installed it on mine, works great with parts off the ZJ, and its not hard either.

 

Here are some links to different swaps.

I read this mod was just a little drilling and no welding involved though?

 

There is no drilling or welding unless you have a d44, then you need to fab a little spacer. Otherwise all you need to do is grind the center hole a tiny bit and it bolts right on.

 

Well shoot. I just put a 44 in two weeks ago.

 

ZJs also came with a 44. Might not have to do the welding but not sure I put them on a turdy five and it was a bolt on thing. Now if they just worked on my 60.

 

Do you happen to know what years ZJ came with a 44?
