As a starting point, its typically better to clarify your objectives for a build path...as it saves a lot of do-overs and mis-steps, etc.
For example, if ALL you want are larger tires, and you're not actually going to go off road (Off road like places a stock rig can't go...)....you can actually just fit 33's as mentioned, with no lift or other mods except the melt mod, and call it a day.
If you also want to just be higher, a 3" Body Lift would avoid messing up anything to do with steering, etc...and, has the advantage of adding even more tire room (Its typically TO add tire room).
If you ARE going to venture out where a stock truck can't...after that, its all a question of degree...HOW off road capable did you want to get?
For example, you might need skid plates and sliders more than a lift...as you'd never lift high enough to never hit, etc.
And so forth.
For off road as in fire trails and dirt roads, etc...the X is already more than capable, and is quite a beast right off the showroom floor. Its when you want to do more than that, that you start to up the ante.
