The right or wrong Pitman Arm will be very unlikely to cause Death Wobble.
A stock arm is OK for a 2 inch lift by tradition, but I think even a 2 inch lift deserves to drop Pitman Arm and track bar bracket.
Notice I mentioned the track bar, because you don’t do one or the other without the other. If you change the angle of the drag link, you must change the angle of the track bar to match.
You’re certainly OK to drive it just the way it is with a 2 inch lift. Plenty of us have done it. But if you don’t like the way, it feels, then plan your modifications accordingly.
