Jeep Cherokee help

Yes you can swap them over...... What we did was went to pick a part and grabbed a set of coils off of a 94 v8 grand Cherokee and then for the back we used long shackles which gave us a 3 1/2 lift... You can also use stock Ford Bronco coils they give you a 4 inch lift but there really stiff,
For 4 inches you would need new shocks, brake lines, sway bar links and it will take you a day or so... Actually on the brake lonesome you can just move them down from the stock location which will give you more inches out of them....
