I put the Dobinsons heavy 1.75"/2" lift with their 'yellow' shocks and I am on 33 Fallken AT3W. I have had absolutely no issues by NOT doing anything with caster correction. I have driven about 10k miles with this. The only thing I had to do with this lift is to extend the breather tubes for the diffs. Before you do the lift and the work you should bring it to an alignment shop to get a baseline of where you are now, do the lift, drive it to test, and then bring it back to see the difference. The main decision should really be based on YOUR driving and your feelings with it.
