I've already run around all over down there with 13.50's.
I did buy the pitman and idler support kit, and the idler pivot kit. I talked to Phil about swapping out the center link also, but the truck does spend more time on the road than off.......so I didn't do that part.
You're right though.....the steering with those wide tires was one of my primary concerns too.
Edit*
I'm already used to wheeling a 3 and not breaking sh!t, so I should be OK. No smilies on edit so pretend there is a big grin here.
