You can just swap out the rails, this is how I ran my 14 pro. All I did was zip tied my snow flap to my rear bumper. Didnt have any issues with the tunnel, and I was running a 3" track. You will need to increase pre-load on the rear track shock. Eric
Did this on my 17 axys went with the 3" rails they are shorter than the ones for the 2.6 because I'm running a x3. Also fire and ice makes a nice tunnel ext. for like $70 155" to 162/3
