i had an 06 3500 drw and had the big wheel kit with auto and some light mods and didnt have any problems. actually the DOT when i stopped at the scales said they were better for towing what i tow because of the weight rateings on em. i towed my telehandler with attachments on my 53' gooseneck and weighed in at 38,000lbs and had zero problems. If i still had a dually i would have em on it again in a heartbeat.It did change the ride just a bit though
