Lifting a 2014 325SS

My truck sits a bit tall. Its a dodge, also has a 2 1/2 leveling kit upfront with 35' tires. Ive adjusted my hitch the best I could. I have 6 or 7 inches clearance between the trailer and the bed rails. It gets close sometimes it articulates. My question however is the trailer just seems so low. From the tires to the top of the fender well there is hardly no room. I've already broke my license plate off leaving a parking lot as well as rubbed my spare tire. Again, the trailer sits level for the most part - its not perfect. But how much can I lift this trailer? Can I flip the axles on this model? What needs to be done? Thanks

You might try installing longer shackles. They might raise it 1-2". You have to be careful how high you raise things. You torque is all ready over 13' high. SD does not have many bridges. not that I have seen but, you might find a low one. The higher you raise it...the more top heavy it gets.
