I have a 2500 with a 3" body lift. Had it done by a local 4x4 shop here in VA(Team Hi Dust 4x4). $300 out the door. I don't know what brand lift it is, but I am very happy with it. I have done a few lifts myself and am compfortable doing them. However, this price for out the door was better than me wasting a weekend and beating up my knuckles. For the price I also think that the lift lips are the way to go. Get the lift lips and do it yourself.
