Try some of the spring shops. Stuver spring is a good place. They have worked on a lot of my trucks, but it was not for a lift. 330-535-2111. They did some lift on my sons Dodge, He did the front and they lifted the back for him. Nice people. ERV
There is a place in Columbia Station that does amazing work. It is kinda a one man shop and he really loves Chevy's but will do Fords. This is where I get all my parts from and he can also get you any lift, tire or accessory that you need and do the installs including mount and balance. The place is called "Meyers Tires And Trucks" and the phone # is 440-236-6390 and the guys name is Joe Meyer. Just so you know if you go there expect to see some Chevy stuff. He has a Monster of a Chevy of 49" Iroks and a couple other rigs as well. He is a great guy and I can vouch for his work.
