With an upcountry-ish lift of 1-1.5" you will not need to change anything. I have this setup (with 30/9.50/r15 tires) and the front end geometry is still within factory spec when reviewing the data from a computer alignment.
One thing it can bring to the surface is that old u-joints that have happily been at one operating angle range for a long time sometimes don't like the adjustment to the new angles. I had new u-joints all around when I did my lifting, and I still went through about 200 miles of a more rumbly driveline while the u-joints settled into their new positions. It settled out on its own.
It also brought to the surface a need to replace worn sway bar bushings and end-links. The front end was a bit road-surface vibe-ish until I got in and replaced those. (very very cheap, easy, and quick job). My passengers did not notice it, but I could feel it in the steering wheel (a light vertical shutter that was sensitive to the road surface). If your bushings and end-links are in great shape, you may not even have this issue. And it was just an annoyance, I could have left the old ones in for a long time if I was willing to tolerate the different feel. But something about lifting your vehicle makes you hyper sensitive to every noise, vibration, and odd feeling for a while.
