okay I know most people probably won't even look at this because it sounds retarded but my XJ has a three and a half inch lift and i reccently replaced the upper and lower control arms with adjustable and I found that my lowers werent in bad shape and I'm about to lift my girls WJ with the three inch iron rock offroad lift but it doesn't come with control arms my question is will my old XJ three and a half inch lift lower control arms work for her WJ?

they should because I just replaced my XJ's front LCA's with ones from a WJ.

I thought you were talking stock ones. Yea I'd day THAT would be dumb.

Yea you could definitely throw the adjustable ones in there.

You may have to shim the sides of the bushing sleeves. The WJ bushings are 6mm wider than the XJ bushing sleeves. No big deal.

He's right.

The old arms from under my xj are fixed not adjustable so I can't adjust the length. when I did my adjustables on my xj there was a chart that I used to set the lengths correctly it showed lift height and arm length . I can't seem to find one for a wj

The stock XJ arms and WJ arms are the same length from the center of the front bushing to the center of the back bushing.

Thanks the info is much appreciated I was searching and found a lot of WJ arms going on XJ but not vice versa I'm just gonna install them when I do the lift
