3" SPACERS? will they even fit? that would be like 6" of lift. probably not gonna be able to align that....if it fits. So assuming its a 1.5" spacer, I would guess $200 was not a bad deal. that would be 4 hrs at $50 ea. I did my lift front and rear in 4 hrs total with the help of a friend, a car lift, and air tools. not a hard job with the right tools.
