I don't know about too much lift, but you will have some coil bucket contact with a 2.5 front lift. also the front of your truck will be higher than the back. That may be your desire, but thought you should know.
X2 on that one being too expensive for what it is. you could get alldayfab setup much cheaper, or for about the same money a prg setup.
