Correction Mods for 6\" Lift? I've been debating between a 4" & 6" lift. I'm afraid if I go with the 6" I will be dumping more cash into correcting the steering & driveline. Besides a new steering arm, what needs to be done if I go 6 inches? I know all trucks act different, I just want to get a general idea. Thanks in advance, Rod BLAZER FOOD!!
