Due to availability I have been considering a BDS 3" lift for the unlimited.
Can someone comment on what I will be giving up using an inexpensive kit such as this compared to a full featured kit costing $1800 or more.

 

you get a different colored less expensive sticker to put on your window...so that EVERYONE can know you have a lifted Jeep...

Just kidding I have no idea.

 

Sure, without a new adjustable front track bar, your axle will shift over enough to cause potential problems with handling. Without longer or adjustable lower control arms, your axles will shift inwards towards eachother causing potential ride quality issues and depending on how high you go, your coils can rub and/or get hung up on the front bump stops. Without adjustable front upper control arms, you won't be able to dial in your caster and without adjusting this, your Jeep will wander all over the place (cam bolts are just a cheap fix that I wouldn't recommend). Also, without new longer sway bar links or front disconnects, you won't be able to get the axle articulation you'd want on the trail. Hope this helps.

 

It helps me... mostly. Now how do you adjust caster?
