It's a great idea... if you get longer shocks, all new control arms, change the A arm setup in the back, replace your front and rear sway bar links, change your front driveshaft to double cardon u joints, look into modding the rear shaft as well, and basically get rid of every single part for your 4 inch lift and buy a 6 inch lift. But if you're not going to do all that, then no.
