Point was most good proper offroaders really don't need anything. You can lift them a couple of inches and nothing gets messes up.
Land Cruiser for example you can lift it 2" easy of not more without having to do anything else, same with the Defenders and Discoveries.
Jeep XJ you try lifting it and everything goes out of whack. You need to lower the transmission, modify the front drive shaft, modify the front end, from arms etc etc.
Land Cruiser being my fav. Just thrown in a set of lifted springs at the back, torque up the front torsion rods and your done!
