Since you're in LA there's probably a million places to go for an alignment on a lowered truck, but just in case...fair warning...just about every where else it's not always so easy. There are knock-outs in the upper control arm mounts that will need to be removed if they haven't before. An alignment in my shop is $89, adding the labor for the knock-outs and the pain in the neck factor for a lowered truck and I would be adding an hour of labor at least so it could be a $189 alignment, that's IF I wanted to take the job because frankly we would rather do bread and butter work without having do deal with lowered/modded cars and trucks. You might experience that, don't be upset it's just business. I tip my techs $60 cash to align my own lowered trucks (about 2 hours pay) if that tells you anything even though they would do it for free for me. Just a few thoughts in case you have a hard time at the shop.
BTW, truck looks killer!
