Yes they will work, with some work as already posted, You really aren't going to see much of an upgrade in strength although if you decide to do it I would recommend some coilovers and installing a 4-link setup into the wrangler and ditching the leafs altogether. The Cherokee axle is already setup for 4-link so the hard part is done. Fab some mounts to the frame for the links and your done. I had a 91 cherokee with a long arm lift kit on it and it easily outwheeld most of the wranglers I would wheel with-strictly because of the suspension setup. Think of it this way, IFS is to solid axle as leaf spring is to 4-link.
