Hello, I am looking for a good shop to install 4.56 Yukon gears into my truck. I have a 2003 F-150 4x4 with 3.55 stock gears and 33" tires right now. My truck already has a 5" lift kit and I am ready to go up to a 35" tire. I live near Joliet, IL which is about 30 miles south of Chicago. I am looking for a good shop to do the install. I am also considering getting a shift kit for the transmission as well. If anybody has any ideas, please let me know.
