2013 2500 suburban alignment and steering stabilizer

[DRayson]

Picked up an old border patrol suburban 2500. Going to do the alignment on it in the next day or so and wanted to know if guys had any luck making these beasts drive a little better at highway speeds (less wandering etc) with an alignment different than factory specs (will be doing the alignment myself)

Also, any sense in adding a steering stabilizer? It’s on 1 size bigger tires and torsion keys turned up to level it (like this when I bought it) I don’t have any “death wobble” and not familiar with hd trucks/ lifts to know if that is the only reason to go with a steering stabilizer. There is a factory location for it but from the lack of marking on the arm, there was never one on it.
Thanks!!
