In the write up, eddie recommends that you also get:
a front adjustable track bar
a rear track bar relocation bracket, or a rear adjustable track bar
These keep the axles centered under the Jeep. I recommend JKS front and rear Adjustable Track Bars.
He also recommended in his write up that you get adjustable front lower control arms. These, being adjustable, can be made longer or shorter to push the axle farther forward on either side to fix the caster adjustments, which will be thrown off when you raise the vehicle, and will cause you to pull to one side. I recommend something like the Terraflex Adjustable Lower Front Control Arms.
What you mentioned about needing wheel spacers only comes into play if you go with a wider tire and don't get new wheels with the right amount of back spacing usually 4.5 is the magic number for a typical budget build.
The stock wheels do not have enough back spacing (can't remember the exact amount) but what that means is they don't stick out far enough from the axle to allow a wider tire. If you put on a 35' tire it will be 12.5, the narrowest you can find close to 35' is 305 mm I beleive. I recommend a set of Spidertrax Wheel Spacers, yes you
do have to buy 2 sets.
So all in all the kit that I linked you too is everything needed to raise the vehicle and have it work properly but to have your jeep properly aligned you will need to center the axles with track bars and to fix the caster you will need the control arms.
Hope this helps and if you need a link to any of the parts mentioned let me know and I'll see if I can find anything or you.
Good luck!! :thumb:
