You should be able to git and do the spacers yerself without any problems. If you have a mechanic/shop order them and install them...not sure how much they are gonna charge you fer the whole deal.
I think you'll be happy with the amount of lift you will git with ball joint spacers. Without gitting bigger tires, yer not gonna git too close to the 4WD height...
I have the
Roadmaster Active Suspension on my rear leafs. I like those better than the AALs as they are an active instead of a passive setup.
