Alright I've got my 94 ZJ and was looking at the rustys 3.5" kit. (picture below) I was curious if I could run stock control arms being it's my DD and my XJ is my wheeling rig. This ZJ will see some light trails but mainly mud.. Would I be ok to get this kit, an adjustable track bar and be good to drive?

Thanks, Justin.

Anyone have input?

Stock arms will work, but they're pretty weak and flimsy.

well I have one extra set of adjustable lowers.. Maybe I should get another pair so all the lowers are adjustable and leave uppers stock? What do you think?

WJ uppers are a lot stronger and pretty inexpensive at rockauto. WJ lowers at better than the ZJ lowers too.

are they a direct bolt up?

Some slight modifications will be needed, but nothing major. The upper arm mounts on the body need to be clearances a bit at the top, the the lower bushing sleeves may need to be cut down a little. Test fit before cutting the sleeves. On an XJ the bushing sleeves are about 6mm narrower than the WJ, not sure about the ZJ width of the sleeves.
