I've got AC's sus lift. I had the AAL's on for about a year, with just the torsion crank, it has settled a little, but I still have 2.25" of lift in the rear. I recently (about 3 months ago) put on the UCA's for the front. No alignment issues so far. She tracks nice and straight, nice even tire wear etc...
All in all, AC is good to go, IMO, good lift, good service, good people.
Hey, there's always gonna be those cases were there are flaws in some packages. No company can claim that they have
never had a complaint with any of their products. If they do, they're a liar. Just choose whatever lift you want and be happy
