Im trying to sell my 06 Silverado, I bought it from a local cabinet shop he used the truck to pull an enclosed trailer to job sights. I bought the truck 3 years ago with 190k miles on it. since i bought it i put a lift on it and regeared the rear end to a 4.56, the front end is not geared to match. The front end will need to be regeared before the 4WD can be used. i also installed a Bully Dog GT tuner, since it has been installed i notice that it shifts harder than before but there is a noticeable change in power and fuel mileage. The check engine light is on for an Evap sensor code P0449P0455, the airbag light also stays on. if you have any questions or would like any more pictures feel free to message me.
