Hey all,
I am not new to wheeling or building a Jeep. I am new to building a Grand Cherokee. I have a 2004 Grand Cherokee that I am going to build. I can do the research but was hoping others may have done this already and can point me in the right direction. I want Dana 60 front and rear. I don't know from what vehicle to get them from yet. Was hoping others could send me in the right direction. I will be building up to run 37's or 39's. Not much bigger since I do still want to drive it on the road. Second what lift should work with the right flares. I am thinking 4 in lift with the right flares. I will not go to high and have no problems cutting the stock fenders if I add flares on to clean it up. Yes I am gearing it with those tires and locking it. Already know what I will be doing with that. Any input would be much appreciated.
