Well charles I have the 37's and I have the leveling kit. I went out to put them on and my good floor jack is gone. I would be able to tell you for sure. Anybody have a floor jack or better yet a lift I can come over and use?
Do u have a factory bumper? If so u need to get rid of it or do some trimin. I didnt believe it when he told me, but i saw a 2010 2500 with a 2" leveling kit clearing a set of 37x13.5x20 toyo mt. he had a ranch hand bumper.
