My suggestion if your trying to save money is to chop fenders and crank your torsion bars and a cheap lift in the rear for bigger tires. I wouldn't waste money on a IFS lift, instead I would save the money up for a solid axle swap. I don't have much money to put into my rig but that's kinda the philosyphy I have.
Like mentioned before, I do have to pick my lines better. It is still stock (except for 31's) so that also factors in a lot. But I really have to make sure I don't Flex my truck too much cause my rear end always want to slip all the power to whichever tire it can and then im screwed. I think a locker in the rear would be a great improvement too, probably selectable would be best cause its a daily driver.
