It was nice meeting you and the family last night at the Food Trucks.
I see a lot of back and forth in this thread about PRG. I can highly recommend PRG. Greg personally installed his original version of the Xterra lift on my 2005 Xterra. That was the Total Chaos UCA with Radflo in the front, and AAL in the rear. After he installed the lift, he aligned the front end with a tape measure and a crescent wrench while it was sitting in his driveway, and that alignment held up for probably 50K miles - and a fair amount of that was off-road. Greg can sometimes be a little tough to get in touch with, but he offers great customer service and advice.
