I recently purchased a 2000 GMC Sierra Extended cab 2wd. I am looking for a lift kit primarily for looks and some light off roading on occasion. I am thinking maybe a fabtech 3" spindle system(because i know where to get one cheap) plus a 3" body lift for a total of 6". I was wondering if this combo will work and if there is anything wrong with running a body lift and a lift kit together. Also what size tires and wheels will work for this and will I need any differential mods for this.
