I am finally going to put some money into my cherokee. Nothing major just enough to have some fun on the weekend and still DD during the week. I am going to go with the rough country 3in aal and to combat the rear spring sag I am going to get the adjustable rear shackle (has anyone tried this?) $50 for the shackle vs. $250 for the full leaf pack. I am not a mechanic by any stretch of the imagination so I have a few questions. Is there any thing else I will need to add to this project that the lift I picked doesn't have? Also I picked up a set of wrangler ravine rims and want to know if there will be any issues running 31x10.5's on them or any issues with them rubbing?
