2" leveling kit on the front of my 08 CTD 3500 with 315/70/17s and they rub a little on the factory front splash guards. If the splash guards weren't there they wouldn't rub at all.
The fit stock but rub on the control arms. thats what mine had on it when i bought it. Mine were on stock wheels also. Since then I have done a 2 1/2-3 inch up front and it sits just a little nose high but rides nice. let me know I still have 3x 35-12.5-17 pro comp Mt's if you need a spare
