I just put a Autospring 2.5 and 3in rear blocks on mine. I had it aligned today and as far as I could tell everything is back to like it was factory. On the highway It tracks straight with no hands on the wheel. My wheels and tires come in tomorrow and hopefully nothing changes. Did you have them put the Cam/Cas kits (http://www.spcalignment.com/componen...AFrom&to=USATo )on the LCA's when they had it aligned? A lot of people say you don't need them and the tech told me he could get aligned without them but it wasn't going to be the greatest alignment.

 

I did not do the cam kit, but it sounds like I will be ordering up a set and having it redone to see if that helps. It is currently an unacceptable amount of drift (still strange that it can be one side pulling for awhile, then the other side, then back, it's not jumping all over the place but sticking to one side for a decent duration).

 

I bet those kits will fix it. That's what the tech told me would probably happen to mine without those. I went to a 4 wheel auto shop that's has there own alignment rack. I didn't trust going to a local chain place that does alignments. It cost a little more to align but it's damn near perfect.
