From 3" to 4.5"

Right now I have a 3" skyjacker lift with a relocating track bar bracket.
If I decide to throw in some 1.5" spacers what are my track bar options?
Could I redrill the mounts on the axle or will I be needing a new adjustable one?
For fun I jacked the truck up about 1.5" and you can see that the axle IS off.
Id like to be able to swing 32x11.5's but dont know what all Ill end up needing

trim away you can tuck 32s on 3 inches of lift.

Yes you'll need a new TB....get an adjustable and for the love of god, get rid of that drop-bracket....

you probably notice now how your track bar and drag link aren't parallel....get much bump-steer?

Do yourself a favor and ditch the relocation bracket even if you dont add more lift. Theyre junk. It's just one more part to fail. I replaced mine within days after installing a 3" lift with a JKS adustable tb, spendy but worth it.
