Well, with all the incentives and early turn in and all... my wife is now driving a 2004HD 4x4 ext cab. One of the first things she says... somehting like.. "When can we lift it so bigger tires will fit?" I love my wife. Anyone have suggestions about lifts? I know nothing about the IFS lifts. Still will tow a with it, but would like to fit 35s. Has 30.5s on it now and there is definately room for a little more, but not 35s. Ken H.
