Al, we had the 6" fabtech done not too long ago. Same tires. I wheeled it for the first time today.
It really makes a difference and it was a lot of fun.
After your install, it may be tight and awkward feeling- but it will work itself out and you will get used to it.
Fun fun!!! On the street, on the trail, it is like a toy. You will love it- congratulations.
Ps- you may want to look into getting the fender flares from Trail duty as well. That made it look even better.
