I have heard tha the KJ has a stock 8.25 with disc brakes? Any one know if this is true and would this be the easiest swap from drum to disc?

They would bolt on to a XJ 8 1/4, I'm pretty sure the brake mounting is the same.

egon said:The dakota 8.25" is a 6 lug axle, V8 dakotas will come with either 8.25"s or 9.25". They haven't made 8 3/4" since the 70's, tis a great axle though.
Hell, the new WKs and XKs are using "front" and rear 8.25"s but are calling them AAM 200 and AAM 813.

What did you have to fab and was there a huge diff in braking. My 44 has a lot more braking surface then the old 35. Like 40%, but with low gears and in 4 lo it still pushes thru the brakes. I'm learnng to go into Neutral off falls. I hate that feeling of needing to stop and it pushing thru it. Especially when you are in those off-camber situations.egon said:I did a KJ disc swap on my D44 with minimal fabrication and all off the shelf stock Jeep brake parts.

A friend of mine in concord has done the disc brake swap. He can tell you what you need. As for the kj good luck in the SE. The yards arround here are high and limited.lilredwagn said:I called around to about a dozen yards in the southeast, and nobody would separate the brake components (ZJ) from the axle.
I'm very sloppy with my notes, but if I'm reading them correctly, there's a guy at Marsh Auto Parts in Siler City, NC .. he wouldn't part a good axle, but he did the swap on his own XJ and knows what's up with the ZJ disc swap - so he could probably get you what you want if you are willing to piece it together over time using the good sides from axles that took a hit.

My parents went through 3 diffs in theirs and finally dumped the Jeep. They should of just stuck a 8.25 in it instead, but it was under factory warranty and they insisted in OME.
It was sweet Jeep other then that though. I think it was 1999 Limited.
jjmat3 said:XJ's had an aluminum 44 rear diff? Hmmm..don't think so. The front Al. D30 is lame and I blew one up already. I have seen them wheeled fairly hard and survive and seen others grenade during easy wheeling. I'm done w/ the one in mine and it is now a spare for my wifes KJ. My KJ is getting Rubicon D44's and 241 transfer case w/ an adapted Nth degree long arm lift. The rear 8.25 in my KJ will either be adapted to work in my XJ or gutted and the parts stuffed into my current XJ 8.25.
