Stock, the front tires can contact the plastic inner fender liners and rip them out... not common but I have seen it happen if the front is bottomed out hard.
You'll be adding 1" to the tire radius so a spacer lift would help give you more clearance at full compression... if you're inclined to lift the truck.
I've seen it too which is why I'm not in favor of going to 37's (even if they're not a full 37") not to mention the extra weight which is a negative.
It's one of those instances where it's about looks and being different as I see no other reason to go with 37's.
