Im going to be lifting my friends 04 FX4 F150 with a 4.5 superlift. I read the instructions and it seemed quite intense. I have lifted a few jeeps before, but I have never done a IFS vehicle. Does anyone have any suggestions or tips on installation with this lift? How is the quality of this kit? The kit also says that you cant use the factory rims either because of backspacing. Is this true with all kits, because I have seen other guys lifting F150s and using the stock rims and just putting 35's on them?
